Acupuncture


Acupuncture (from Lat. acus, "needle" (noun), and pungere, "prick" (verb)) or in Standard Mandarin, zhēn jiǔ (針灸 lit: needle - moxibustion) is a technique of inserting and manipulating filiform needles into "acupuncture points" on the body. According to acupunctural teachings this will restore health and well-being, and is particularly good at treating pain. The definition and characterization of these points is standardized by the World Health Organization (WHO). Acupuncture is thought to have originated in China and is most commonly associated with Traditional Chinese medicine (TCM). Different types of acupuncture (Japanese, Korean, and classical Chinese acupuncture) are practiced and taught throughout the world.

Whether acupuncture is efficacious or a placebo, and the range of its possible applications, have been the subject of ongoing scientific research. Scientists have conducted reviews of existing clinical trials according to the protocols of evidence-based medicine; some have found evidence for treatment of nausea and low back pain, but for most conditions have concluded that there is insufficient evidence to determine if acupuncture is effective. The WHO, the National Center for Complementary and Alternative Medicine (NCCAM) of the National Institute of Health (NIH), the American Medical Association (AMA) and various government reports have also studied and commented on the efficacy of acupuncture. There is general agreement that acupuncture is at least safe when administered by well-trained practitioners, and that further research is warranted.

Traditional Chinese medicine's acupuncture theory predates use of the scientific method, and has received various criticisms based on scientific thinking. There is no known anatomical or histological basis for the existence of acupuncture points or meridians. Acupuncturists tend to perceive TCM concepts in functional rather than structural terms, i.e. as being useful in guiding evaluation and care of patients. Neuroimaging research suggests that certain acupuncture points have distinct effects that are not otherwise predictable anatomically.

Traditional theory
Chinese medicine is based on a different paradigm than scientific biomedicine. Its theory holds the following explanation of acupuncture:
Acupuncture treats the human body as a whole that involves several "systems of function" that are in some cases loosely associated with (but not identified on a one-to-one basis with) physical organs. Some systems of function, such as the "triple heater" (San Jiao, also called the "triple burner") have no corresponding physical organ. Disease is understood as a loss of homeostasis among the several systems of function, and treatment of disease is attempted by modifying the activity of one or more systems of function through the activity of needles, pressure, heat, etc. on sensitive parts of the body of small volume traditionally called "acupuncture points" in English, or "xue" (穴, cavities) in Chinese. This is referred to as treating "patterns of disharmony".

Treatment of acupuncture points may be performed along the twelve main or eight extra meridians, located throughout the body, or on tender points, called "ashi" (signifying "that's it", "ouch", or "oh yes"). Of the eight extra meridians, only two have acupuncture points of their own. The other six meridians are "activated" by using a master and couple point technique which involves needling the acupuncture points located on the twelve main meridians that correspond to the particular extra meridian. Ten of the main meridians are named after organs of the body (Heart, Liver, etc.), and the other two are named after so called body functions (Heart Protector or Pericardium, and San Jiao). The meridians are capitalized to avoid confusion with a physical organ (for example, we write the "Heart meridian" as opposed to the "heart meridian"). The two most important of the eight "extra" meridians are situated on the midline of the anterior and posterior aspects of the trunk and head. The twelve primary meridians run vertically, bilaterally, and symmetrically and every channel corresponds to and connects internally with one of the twelve Zang Fu ("organs"). This means that there are six yin and six yang channels. There are three yin and three yang channels on each arm, and three yin and three yang on each leg.

The three yin channels of the hand (Lung, Pericardium, and Heart) begin on the chest and travel along the inner surface (mostly the anterior portion) of the arm to the hand.

The three yang channels of the hand (Large intestine, San Jiao, and Small intestine) begin on the hand and travel along the outer surface (mostly the posterior portion) of the arm to the head.

The three yang channels of the foot (Stomach, Gallbladder, and Bladder) begin on the face, in the region of the eye, and travel down the body and along the outer surface (mostly the anterior and lateral portion) of the leg to the foot.

The three yin channels of the foot (Spleen, Liver, and Kidney) begin on the foot and travel along the inner surface (mostly posterior and medial portion) of the leg to the chest or flank.

The movement of qi through each of the twelve channels is comprised of an internal and an external pathway. The external pathway is what is normally shown on an acupuncture chart and it is relatively superficial. All the acupuncture points of a channel lie on its external pathway. The internal pathways are the deep course of the channel where it enters the body cavities and related Zang-Fu organs. The superficial pathways of the twelve channels describe three complete circuits of the body.

The distribution of qi through the meridians is said to be as follows (the based on the demarcations in TCM's Chinese Clock): Lung channel of hand taiyin to Large Intestine channel of hand yangming to Stomach channel of foot yangming to Spleen channel of foot taiyin to Heart channel of hand shaoyin to Small Intestine channel of hand taiyang to Bladder channel of foot taiyang to Kidney channel of foot shaoyin to Pericardium channel of hand jueyin to San Jiao channel of hand shaoyang to Gallbladder channel of foot shaoyang to Liver channel of foot jueyin then back to the Lung channel of hand taiyin.

Chinese medical theory holds that acupuncture works by normalizing the free flow of qi (a difficult-to-translate concept that pervades Chinese philosophy and is commonly translated as "vital energy") throughout the body. Pain or illnesses are treated by attempting to remedy local or systemic accumulations or deficiencies of qi. Pain is considered to indicate blockage or stagnation of the flow of qi, and an axiom of the medical literature of acupuncture is "no pain, no blockage; no blockage, no pain".

Many patients claim to experience the sensations of stimulus known in Chinese as "deqi" (得氣, "obtaining the qi" or "arrival of the qi"). This kind of sensation was historically considered to be evidence of effectively locating the desired point. There are some electronic devices now available which will make a noise when what they have been programmed to describe as the "correct" acupuncture point is pressed.

The acupuncturist decides which points to treat by observing and questioning the patient in order to make a diagnosis according to the tradition which he or she utilizes. In TCM, there are four diagnostic methods: inspection, auscultation and olfaction, inquiring, and palpation (Cheng, 1987, ch. 12). Inspection focuses on the face and particularly on the tongue, including analysis of the tongue size, shape, tension, color and coating, and the absence or presence of teeth marks around the edge. Auscultation and olfaction refer, respectively, to listening for particular sounds (such as wheezing) and attending to unusual body odor. Inquiring focuses on the "seven inquiries", which are: chills and fever; perspiration; appetite, thirst and taste; defecation and urination; pain; sleep; and menses and leukorrhea. Palpation includes feeling the body for tender "ashi" points, and palpation of the left and right radial pulses at two levels of pressure (superficial and deep) and three positions (immediately proximal to the wrist crease, and one and two fingers' breadth proximally, usually palpated with the index, middle and ring fingers). Other forms of acupuncture employ additional diagnosic techniques. In many forms of classical Chinese acupuncture, as well as Japanese acupuncture, palpation of the muscles and the hara (abdomen) are central to diagnosis.

There are also theories being developed to explain effects observed for acupuncture within the orthodox Western medical paradigm.

Categories of acupuncture points
Certain acupuncture points are ascribed different functions according to different systems within the TCM framework.
*Five Transporting Points system describes the flow of qi in the channels using a river analogy, and ascribes function to points along this flowline according to their location. This system describes qi bubbling up from a spring and gradually growing in depth and breadth like a river flowing down from a mountain to the sea.
*Jing-well points represent the place where the qi "bubbles" up. These points are always the first points on the yang channels or last points on the yin channels and with exception of Kid-1 YongQuan all points are located on the tips of fingers and toes. The Nan Jing and Nei Jing described jing-well points as indicated for "fullness below the heart" (feeling of fullness in the epigastric or hypochondrium regions) and disorders of the zang organs (yang organs).
*Ying-spring points are where the qi "glides" down the channel. The Nan Jing and Nei Jing described ying-spring points as indicated for heat in the body and change in complexion.
*Shu-stream points are where the qi "pours" down the channel. Shu-stream points are indicated for heaviness in the body and pain in the joints, and for intermittent diseases.
*Jing-river points are where the qi "flows" down the channel. Jing-river points are indicated for cough and dyspnoea, chills and fever, diseases manifesting as changes in voice, and for diseases of the sinews and bones.
*He-sea points are where the qi collects and begins to head deeper into the body. He-sea points are indicated for counterflow qi and diarrhea, and for disorders resulting from irregular eating and drinking.

*Five Phase Points ascribe each of the five phases - wood, fire, earth, metal, water - to one of the Five Transporting points. On the yin channels, the jing-well points are wood points, the ying-spring points are fire, shu-stream points are earth, jing-river points are metal, he-sea points are water points. On the yang channels, the jing-well points are metal, ying-spring are water, shu-stream are wood, jing-river points are fire and he-sea points are earth points. These point categories are then implemented according to Five Phase theory in order to approach the treatment of disease.

*Xi-cleft points are the point on the channel where the qi and blood gather and plunge more deeply. These points are indicated in acute situations and for painful conditions.

*Yuan-source points are points on the channel from where the yuan qi can be accessed.

*Luo-connecting points are located at the point on the channel where the luo meridian diverges. Each of the twelve meridians have a luo point that diverges from the main meridian. There are also three extra luo channels that diverge at Sp-21, Ren-15 and Du-1.

*Back-shu points lie on the paraspinal muscles either side of the spine. Theory says that the qi of each organ is transported to and from these points, and can be influenced by them.

*Front-mu points are located in close proximity to the respective organ. They have a direct effect on the organ itself but not on the associated channel.

*Hui-meeting points are a category of points that are considered to have a "special effect" on certain tissues and organs. The hui-meeting points are:
*zang organs - Liv-13 Zhang Men
*fu organs - Ren-12 Zhong Fu
*qi - Ren-17 Shang Fu
*blood - Bl-17 Ge Shu
*sinews - GB-34 Yang Ling Quan
*vessels - Lu-9 Tai Yuan
*bone - Bl11 Da Zhu
*marrow - GB-39 Xuan Zhong

TCM perspective on treatment of disease
Although TCM is based on the treatment of "patterns of disharmony" rather than biomedical diagnoses, practitioners familiar with both systems have commented on relationships between the two. A given TCM pattern of disharmony may be reflected in a certain range of biomedical diagnoses: thus, the pattern called Deficiency of Spleen Qi could manifest as chronic fatigue, diarrhea or uterine prolapse. Likewise, a population of patients with a given biomedical diagnosis may have varying TCM patterns. These observations are encapsulated in the TCM aphorism "One disease, many patterns; one pattern, many diseases". (Kaptchuk, 1982)

Acupuncture has been used to treat a number of conditions (see Clinical practice, below). Classically, "(i)n clinical practice, acupuncture treatment is typically highly-individualized and based on philosophical constructs, and subjective and intuitive impressions" and not on controlled scientific research."

History
In China, the practice of acupuncture can perhaps be traced as far back as the 1st millennium BCE, and archeological evidence has been identified with the period of the Han dynasty (from 202 BC to 220 AD). Forms of it are also described in the literature of traditional Korean medicine where it is called chimsul. It is also important in Kampo, the traditional medicine system of Japan.

Recent examinations of Ötzi, a 5000-year-old mummy found in the Alps, have identified over fifty tattoos on his body, some of which are located on acupuncture points that would today be used to treat ailments Ötzi suffered from. Some scientists believe that this is evidence that practices similar to acupuncture were practised elsewhere in Eurasia during the early bronze age. According to an article published in The Lancet by Dorfer et al.: "We hypothesised that there might have been a medical system similar to acupuncture (Chinese Zhenjiu: needling and burning) that was practised in Central Europe 5200 years ago...A treatment modality similar to acupuncture thus appears to have been in use long before its previously known period of use in the medical tradition of ancient China. This raises the possibility of acupuncture having originated in the Eurasian continent at least 2000 years earlier than previously recognised." ,

Acupuncture's origins in China are uncertain. The earliest Chinese medical texts (Ma-wang-tui graves 68 BC) do not mention acupuncture. The Chinese medical text that first describes acupuncture is The Yellow Emperor’s Classic of Internal Medicine (History of Acupuncture), which was compiled around 305–204 B.C. Some hieroglyphics have been found dating back to 1000 B.C. that may indicate an early use of acupuncture. Bian stones, sharp pointed stones used to treat diseases in ancient times, have also been discovered in ruins (History of Acupuncture in China); some scholars believe that the bloodletting for which these stones were likely used presages certain acupuncture techniques

RC Crozier in the book Traditional medicine in modern China (Harvard University Press, Cambridge, 1968) says the early Chinese Communist Party expressed considerable antipathy towards classical forms of Chinese medicine, ridiculing it as superstitious, irrational and backward, and claiming that it conflicted with the Party’s dedication to science as the way of progress. Acupuncture was included in this criticism. Reversing this position, Communist Party Chairman Mao later said that "Chinese medicine and pharmacology are a great treasure house and efforts should be made to explore them and raise them to a higher level" Representatives were sent out across China to collect information about the theories and practices of Chinese medicine. Traditional Chinese Medicine is the formalized system of Chinese medicine that was created out of this effort. TCM combines the use of Acupuncture, Chinese herbal medicine, tui na and other modalities. After the Cultural Revolution, TCM instruction was incorporated into university medical curricula under the "Three Roads" policy, wherein TCM, biomedicine and a synthesis of the two would all be encouraged and permitted to develop. After this time, forms of classical Chinese medicine other than TCM were outlawed, and some practitioners left China. The first forms of acupuncture to reach the United States were brought by non-TCM practitioners, many employing styles that had been handed down in family lineages, or from master to apprentice (collectively known as "Classical Chinese Acupuncture"). In Vietnam Dr. Van Nghi and colleagues used the Classical Chinese Medical Texts and applied them in clinical conditions without reference to political screening. They rewrote the modern version: Trung E Hoc. Dr. Van Nghi was made the first President of the First World Congress of Chinese Medicine at Bejing in 1988 in recognition of his work.

Criticism of TCM theory
TCM theory predates use of the scientific method, and has received various criticisms based on scientific thinking, since there is no physically verifiable anatomical or histological basis for the existence of acupuncture points or meridians.

Felix Mann, founder and past President of the Medical Acupuncture Society (1959-1980), the first President of the British Medical Acupuncture Society (1980), and the author of the first comprehensive English language acupuncture textbook Acupuncture: The Ancient Chinese Art of Healing' first published in 1962, has stated in his book Reinventing Acupuncture: A New Concept of Ancient Medicine:


The traditional acupuncture points are no more real than the black spots a drunkard sees in front of his eyes (p. 14).
and…


The meridians of acupuncture are no more real than the meridians of geography. If someone were to get a spade and tried to dig up the Greenwich meridian, he might end up in a lunatic asylum. Perhaps the same fate should await those doctors who believe in [acupuncture] meridians. (p. 31).
Philosopher Robert Todd Carroll deems acupuncture a pseudoscience because it "confuse(s) metaphysical claims with empirical claims". Carroll states that:

...no matter how it is done, scientific research can never demonstrate that unblocking chi by acupuncture or any other means is effective against any disease. Chi is defined as being undetectable by the methods of empirical science.
A report for CSICOP on pseudoscience in China written by Wallace Sampson and Barry L. Beyerstein said:

A few Chinese scientists we met maintained that although Qi is merely a metaphor, it is still a useful physiological abstraction (e.g., that the related concepts of Yin and Yang parallel modern scientific notions of endocrinologic and metabolic feedback mechanisms). They see this as a useful way to unite Eastern and Western medicine. Their more hard-nosed colleagues quietly dismissed Qi as only a philosophy, bearing no tangible relationship to modern physiology and medicine.
Stephen Barrett, founder of Quackwatch, writes:

Most acupuncturists espouse the traditional Chinese view of health and disease and consider acupuncture, herbal medicine, and related practices to be valid approaches to the full gamut of disease. Others reject the traditional approach and merely claim that acupuncture offers a simple way to achieve pain relief. Some acupuncturists ... claim that acupuncture can be used to treat conditions when the patient just "doesn't feel right," even though no disease is apparent.
George A. Ulett MD PhD, Clinical Professor of Psychiatry, University of Missouri School of Medicine states:

Devoid of metaphysical thinking, acupuncture becomes a rather simple technique that can be useful as a nondrug method of pain control." He believes that the traditional Chinese variety is primarily a placebo treatment, but electrical stimulation of about 80 acupuncture points has been proven useful for pain control.
Ted J. Kaptchuk, author of The Web That Has No Weaver, refers to acupuncture as "prescientific". Regarding TCM theory, Kaptchuk states:

These ideas are cultural and speculative constructs that provide orientation and direction for the practical patient situation. There are few secrets of Oriental wisdom buried here. When presented outside the context of Chinese civilization, or of practical diagnosis and therapeutics, these ideas are fragmented and without great significance. The "truth" of these ideas lies in the way the physician can use them to treat real people with real complaints. (1983, pp.34-35)
According to the NIH consensus statement on acupuncture:

Despite considerable efforts to understand the anatomy and physiology of the "acupuncture points", the definition and characterization of these points remains controversial. Even more elusive is the basis of some of the key traditional Eastern medical concepts such as the circulation of Qi, the meridian system, and the five phases theory, which are difficult to reconcile with contemporary biomedical information but continue to play an important role in the evaluation of patients and the formulation of treatment in acupuncture.
Clinical practice

Most modern acupuncturists use disposable stainless steel needles of fine diameter (0.007" to 0.020", 0.18 mm to 0.51 mm), sterilized with ethylene oxide or by autoclave. These needles are far smaller in diameter (and therefore less painful) than the needles used to give shots, since they do not have to be hollow for purposes of injection. The upper third of these needles is wound with a thicker wire (typically bronze), or covered in plastic, to stiffen the needle and provide a handle for the acupuncturist to grasp while inserting. The size and type of needle used, and the depth of insertion, depend on the acupuncture style being practised.

Warming an acupuncture point, typically by moxibustion (the burning of mugwort), is a different treatment than acupuncture itself and is often, but not exclusively, used as a supplementing treatment. The Chinese term zhēn jǐu (針灸), commonly used to refer to acupuncture, comes from zhen meaning "needle", and jiu meaning "moxibustion". Moxibustion is still used in the 21st century to varying degrees among the schools of oriental medicine. For example, one well known technique is to insert the needle at the desired acupuncture point, attach dried mugwort to the external end of an acupuncture needle, and then ignite the mugwort. The mugwort will then smolder for several minutes (depending on the amount adhered to the needle) and conduct heat through the needle to the tissue surrounding the needle in the patient's body. Another common technique is to hold a large glowing stick of moxa over the needles. Moxa is also sometimes burned at the skin surface, usually by applying an ointment to the skin to protect from burns.

An example of acupuncture treatment
In western medicine, vascular headaches (the kind that are accompanied by throbbing veins in the temples) are typically treated with analgesics such as aspirin and/or by the use of agents such as niacin that dilate the affected blood vessels in the scalp, but in acupuncture a common treatment for such headaches is to stimulate the sensitive points that are located roughly in the center of the webs between the thumbs and the palms of the patient, the hé gǔ points. These points are described by acupuncture theory as "targeting the face and head" and are considered to be the most important point when treating disorders affecting the face and head. The patient reclines, and the points on each hand are first sterilized with alcohol, and then thin, disposable needles are inserted to a depth of approximately 3-5 mm until a characteristic "twinge" is felt by the patient, often accompanied by a slight twitching of the area between the thumb and hand. Most patients report a pleasurable "tingling" sensation and feeling of relaxation while the needles are in place. The needles are retained for 15-20 minutes while the patient rests, and then are removed.

In the clinical practice of acupuncturists, patients frequently report one or more of certain kinds of sensation that are associated with this treatment, sensations that are stronger than those that would be felt by a patient not suffering from a vascular headache:


Extreme sensitivity to pain at the points in the webs of the thumbs.
In bad headaches, a feeling of nausea that persists for roughly the same period as the stimulation being administered to the webs of the thumbs.
Simultaneous relief of the headache. (See Zhen Jiu Xue, p. 177f et passim.)

Scientific theories and mechanisms of action
Many hypotheses have been proposed to address the physiological mechanisms of action of acupuncture. To date, more than 10,000 scientific research studies have been published on acupuncture as cataloged by the National Library of Medicine database.
Gate-control theory of pain
The "gate control theory of pain" (developed by Ronald Melzack and Patrick Wall in 1962 and in 1965) proposed that pain perception is not simply a direct result of activating pain fibers, but modulated by interplay between excitation and inhibition of the pain pathways. The "gating of pain" is controlled by the inhibitory action on the pain pathways. That is, the perception of pain can be altered (gated on or off) by a number of means physiologically, psychologically and pharmacologically. The gate-control theory was developed in neuroscience independent of acupuncture, which later was proposed as a mechanism to account for the analgesic action of acupuncture in the brainstem reticular formation by a German neuroscientist in 1976. (With the advance in modern-day technology, stimulation of these pathways can be demonstrated to alter pain perception using electrical stimulations or magnetic stimulations, such as transcranial magnetic stimulation (TMS) or pulsed electromagnetic field (PEMF) therapy for pain.)
It is well-documented in neuroscience that pain blockade can be achieved at multiple levels in the central nervous system (i.e., the brain and spinal cord). At the spinal cord level, pain transmission via the pain fibers can be blocked by surround inhibition of the neighboring nerve fibers that merge at the substantia gelatinosa in the spinal cord. That is to say, stimulation of the surrounding neurons can cause a reduction of pain when the center excitatory pain fibers are inhibited by the surrounding cutaneous (touch) fibers. This phenomenon is demonstrated in the all-too-common experience that, when we bump our head, pain can be relieved by rubbing the surrounding skin area (activating the surround inhibitory neural circuitry physiologically). Blockade of pain at this level suppresses pain by blocking the pain signal from the periphery. Furthermore, pain blocking by this cutaneous stimulus only lasts for a short period of time, whereas it is claimed that the effect of pain relief by acupuncture lasts for an extended period of time, sometimes months after the needle was removed.

This leads to the theory of central control of pain gating, i.e., pain blockade at the brain (i.e., central to the brain rather than at the spinal cord or periphery) via the release of endogenous opioid (natural pain killers in the brain) neurohormones, such as endorphins and enkephalins (naturally occurring morphines).

Neurohormonal theory
Pain transmission can also be modulated at many other levels in the brain along the pain pathways, including the periaqueductal gray, thalamus, and the feedback pathways from the cortex back to the thalamus. Each of these brain structure processes different aspect of the pain — from experiencing emotional pain to the perception of what the pain feels like to the recognition of how harmful the pain is to localizing where the pain is coming from. Pain blockade at these brain locations are often mediated by neurohormones, especially those that bind to the opioid receptors (pain-blockade site). Pain relief by morphine drug (exogenous opioid) is acting on the same opioid receptor (where pain blockade occurs) as endorphins (endogenous opioids) that the brain produces and releases.
Some studies suggest that the Analgesic (pain-killing) action of acupuncture is mediated by stimulating the release of natural endorphins in the brain. This can be proven scientifically by blocking the action of endorphins (or morphine) using a drug called naloxone. When naloxone is administered to the patient, the analgesic effects of morphine can be reversed, causing the patient to feel pain again. When naloxone is administered to an acupunctured patient, the analgesic effect of acupuncture can also be reversed, causing the patient to report an increased level of pain. This demonstrates that the site of action of acupuncture may be mediated through the natural release of endorphins by the brain, which can be reversed by naloxone. Similar results were also obtained in experiments with animals showing that the analgesic effect is not due to subjective psychological placebo effect, but real physiological phenomena. Such analgesic effect can also be shown to last more than an hour after acupuncture stimulation by recording the neural activity directly in the thalamus (pain processing site) of the monkey's brain. Furthermore, there is a large overlap between the nervous system and acupuncture trigger points (points of maximum tenderness in myofascial pain syndrome).

The sites of action of acupuncture-induced analgesia are also confirmed to be mediated through the thalamus (where emotional pain/suffering is processed) using modern-day powerful non-invasive fMRI (functional magnetic resonance imaging) and PET (positron emission tomography) brain imaging techniques, and via the feedback pathway from the cerebral cortex (where cognitive feedback signal to the thalamus distinguishing whether the pain is noxious (painful) or innocuous (non-harmful)) using electrophysiological recording of the nerve impulses of neurons directly in the cortex, which shows inhibitory action when acupuncture stimulus was applied.

Scientific Method and the Assessment of Chinese Medical Theory and Techniques

Views of proponents
Criticism of TCM theory hinges on the question of how to assess 'intangible' concerns. There is an assumption that all knowledge can be tested by randomly-controlled double-blind studies, and that anything not susceptible to this method of assessment must be jettisoned as unverifiable. Yet the difficulty is not in the methodology, but rather that the nature of Traditional Chinese Medicine itself makes it difficult to subject it as a whole, or subsets of the medical theory, to this type of assessment.

The theory, practice and techniques of Chinese medicine evolved over many thousands of years, well in advance of a formal articulation of the scientific method. Nevertheless, the principles of the scientific method have been used throughout the development of Chinese medical knowledge. Documentation of developments allowed practitioners to evaluate each other's theoretical and practical hypotheses, and what was shown to be effective and/or consistent with observable phenomena was kept, and the remainder discarded over time.

Chinese medicine is inherently individually applied. Given that the health of the entire individual is taken into account for each patient, any two patients, even with the same diagnosis, will receive different treatments based on their constitutional differences, their pattern of response to treatment, and so on. In addition, each treatment may vary from the previous one, in the same way that a masseur might use strokes in a different order, or different strokes, to treat exactly the same condition, from one treatment to the next.

Thus the very complexity and flexibility of this medical system makes it extremely difficult to run clinical trials – a cohort of many thousands would have to be evaluated in order to even begin to assess any claims made for or against the medicine. Clinical trials are still a valuable exercise, but they are not sufficient to determine conclusively whether either the individual constituents of the medical theory (e.g. acupuncture points), or the medical theory as a whole, are valid.

Views of critics
One of the major criticisms of studies which purport to find that acupuncture is anything more than a placebo is that most such studies are not (in the view of critics) properly conducted. Many are not double blinded and are not randomised. However, double-blinding is not a trivial issue in acupuncture: since acupuncture is a procedure and not a pill, it is difficult to design studies in which the person providing treatment is blinded as to the treatment being given. The same problem arises in double-blinding procedures used in biomedicine, including virtually all surgical procedures, dentistry, physical therapy, etc.; the NIH Consensus Statement notes such issues with regard to sham acupuncture, a technique often used in studies purporting to be double-blinded. See also Criticism of evidence-based medicine. Tonelli, a prominent critic of EBM, argues that complementary and alternative medicine (CAM) cannot be EBM-based unless the definition of evidence is changed. Tonelli also says "the methods of developing knowledge within CAM currently have limitations and are subject to bias and varied interpretation. CAM must develop and defend a rational and coherent method for assessing causality and efficacy, though not necessarily one based on the results of controlled clinical trials."

In China, placebo-controlled studies are often not performed as it believed to be unethical to pretend to give patients bonafide treatment.

Some researchers argue that there is no evidence that acupuncture has any affect on the pathogenesis of viruses and microorganisms, or on human physiology, with the exception of the neurological pathways associated with the nerve cells that were stimulated by them. Thus, the most promising clinical application of acupuncture is in the area of pain control. Some researchers argue that to date there is no conclusive scientific evidence indicating that the procedure has any effectiveness beyond that of a placebo. They argue that studies on acupuncture that meet scientific standards of experimentation have concluded two things: acupuncture is usually more effective than no treatment or a placebo in pill form, and that there is no significant difference in the effectiveness of acupuncture and “sham” acupuncture (needling performed superficially a/o at non-acupuncture sites), which is often used as a control. These researchers therefore conclude that acupuncture's effect is either caused by the tendency of extended, invasive procedures to generate more powerful placebo effects than pills or by the general stimulation of afferent nerve endings at the surface of the skin, causing the release of pain relieving biochemical compounds such as endorphins (this can also be done with jalapeno peppers, electricity, and various other form of stimulation). It may also be a combination of these two effects.

The vast majority of research on acupuncture is conducted by researchers in China, and Ernst et al. argue that there exist major flaws in the design of the experiments, as well as selective reporting of results, and conclude that no conclusions can be drawn from them Some researchers argue that numerous experimental difficulties have prevented the conclusive establishment of a causative relationship (if it exists) between pain relief and the administration of acupuncture. These include the subjective nature of pain measurement and the pervasive influence of psychological factors such as suggestion, confirmation bias, and the distraction of being poked by a needle. Also, they argue, the tendency of chronic pain to ebb and flow on its own without any external intervention leads people to falsely perceive that the last measure they took before the pain subsided was the cause of the relief. This is a logical fallacy known as post hoc ergo propter hoc.

Scientific research into efficacy
Evidence-based medicine
There is scientific agreement that an evidence-based medicine (EBM) framework should be used to assess health outcomes and that systematic reviews with strict protocols are essential. Organisations such as the Cochrane Collaboration and Bandolier publish such reviews.
A 2007 Cochrane Review for the use of acupuncture for neck pain stated:

There is moderate evidence that acupuncture relieves pain better than some sham treatments, measured at the end of the treatment. There is moderate evidence that those who received acupuncture reported less pain at short term follow-up than those on a waiting list. There is also moderate evidence that acupuncture is more effective than inactive treatments for relieving pain post-treatment and this is maintained at short-term follow-up.
For the following conditions, the Cochrane Collaboration concluded there is insufficient evidence that acupuncture is beneficial, often because of the paucity and poor quality of the research and that further research would be needed to support claims for efficacy:


Giving up smoking
Chronic asthma

For low back pain, a Cochrane review (2006) stated:

Thirty-five RCTs covering 2861 patients were included in this systematic review. There is insufficient evidence to make any recommendations about acupuncture or dry-needling for acute low-back pain. For chronic low-back pain, results show that acupuncture is more effective for pain relief than no treatment or sham treatment, in measurements taken up to three months. The results also show that for chronic low-back pain, acupuncture is more effective for improving function than no treatment, in the short-term. Acupuncture is not more effective than other conventional and "alternative" treatments. When acupuncture is added to other conventional therapies, it relieves pain and improves function better than the conventional therapies alone. However, effects are only small. Dry-needling appears to be a useful adjunct to other therapies for chronic low-back pain.
A review by Manheimer et al. in Annals of Internal Medicine (2005) reached conclusions similar to Cochrane's review on low back pain.
For headache, Cochrane concluded (2006) that "(o)verall, the existing evidence supports the value of acupuncture for the treatment of idiopathic headaches. However, the quality and amount of evidence are not fully convincing. There is an urgent need for well-planned, large-scale studies to assess the effectiveness and cost-effectiveness of acupuncture under real-life conditions." Bandolier (1999) states: "There is no evidence from high quality trials that acupuncture is effective for the treatment of migraine and other forms of headache. The trials showing a significant benefit of acupuncture were of dubious methodological quality. Overall, the trials were of poor methodological quality."

For nausea and vomiting: The Cochrane review (2006) on the use of the P6 acupoint for the reduction of post-operative nausea and vomiting concluded that "compared with anti emetic prophylaxis, P6 acupoint stimulation seems to reduce the risk of nausea but not vomiting" Cochrane also stated: "Electroacupuncture is effective for first day vomiting after chemotherapy, but trials considering modern antivomiting drugs are needed." Bandolier said "P6 acupressure in two studies showed 52% of patients with control having a success, compared with 75% with P6 acupressure"(1999) and that one in five adults, but not children showed reduction in early postoperative nausea(2000). A review published by the Scientific Review of Alternative Medicine, however, argued that at the time of writing (2005) the data "are insufficiently reliable to confirm such an effect"

For osteoarthritis, Bandolier, commenting on a 1997 review by Edzard Ernst, stated: "There is no evidence that acupuncture is more effective than sham/placebo acupuncture for the relief of joint pain due to osteoarthritis (OA)."

In practice, EBM does not demand that doctors ignore research outside its "top-tier" criteria

Evidence from neuroimaging studies
Acupuncture appears to have distinct effects on cortical activity, as demonstrated by MRI (magnetic resonance imaging) and PET (positron emission tomography).[3] Researchers from the University of Southampton, UK and Purpan Hospital of Toulouse, France, summarize the literature:


Investigating Acupuncture Using Brain Imaging Techniques: The Current State of Play: George T. Lewith, Peter J. White and Jeremie Pariente. "We have systematically researched and reviewed the literature looking at the effect of acupuncture on brain activation as measured by functional magnetic resonance imaging and positron emission tomography. These studies show that specific and largely predictable areas of brain activation and deactivation occur when considering the traditional Chinese functions attributable to certain specific acupuncture points. For example, points associated with hearing and vision stimulates the visual and auditory cerebral areas respectively."

NIH consensus statement
According to the National Institutes of Health:


Preclinical studies have documented acupuncture's effects, but they have not been able to fully explain how acupuncture works within the framework of the Western system of medicine that is commonly practiced in the United States.
In 1997, the National Institutes of Health (NIH) issued a consensus statement on acupuncture that concluded that

there is sufficient evidence of acupuncture's value to expand its use into conventional medicine and to encourage further studies of its physiology and clinical value
The statement was not a policy statement of the NIH but rather the assessment of a panel convened by the NIH.
The NIH consensus statement said that

the data in support of acupuncture are as strong as those for many accepted Western medical therapies
and added that
there is clear evidence that needle acupuncture is efficacious for adult postoperative and chemotherapy nausea and vomiting and probably for the nausea of pregnancy... There is reasonable evidence of efficacy for postoperative dental pain... reasonable studies (although sometimes only single studies) showing relief of pain with acupuncture on diverse pain conditions such as menstrual cramps, tennis elbow, and fibromyalgia...
The NIH consensus statement summarized and made a prediction:

Acupuncture as a therapeutic intervention is widely practiced in the United States. While there have been many studies of its potential usefulness, many of these studies provide equivocal results because of design, sample size, and other factors. The issue is further complicated by inherent difficulties in the use of appropriate controls, such as placebos and sham acupuncture groups. However, promising results have emerged, for example, showing efficacy of acupuncture in adult postoperative and chemotherapy nausea and vomiting and in postoperative dental pain. There are other situations such as addiction, stroke rehabilitation, headache, menstrual cramps, tennis elbow, fibromyalgia, myofascial pain, osteoarthritis, low back pain, carpal tunnel syndrome, and asthma, in which acupuncture may be useful as an adjunct treatment or an acceptable alternative or be included in a comprehensive management program. Further research is likely to uncover additional areas where acupuncture interventions will be useful.
The NIH's National Center For Complementary And Alternative Medicine continues to abide by the recommendations of the NIH Consensus Statement

American Medical Association statement
In 1997, the following statement was adopted as policy of the American Medical Association (AMA) after a report on a number of alternative therapies including acupuncture:
"There is little evidence to confirm the safety or efficacy of most alternative therapies. Much of the information currently known about these therapies makes it clear that many have not been shown to be efficacious. Well-designed, stringently controlled research should be done to evaluate the efficacy of alternative therapies."
Safety and risks
Because acupuncture needles penetrate the skin, many forms of acupuncture are invasive procedures, and therefore not without risk. Injuries are rare among patients treated by trained practitioners.
Certain forms of acupuncture such as the Japanese Tōyōhari and Shōnishin often use non-invasive techniques, in which specially-designed needles are rubbed or pressed against the skin. These methods are common in Japanese pediatric use.

Common, minor adverse events
A survey by Ernst et al. of over 400 patients receiving over 3500 acupuncture treatments found that the most common adverse effects from acupuncture were:


Minor bleeding after removal of the needles, seen in roughly 3% of patients. (Holding a cotton ball for about one minute over the site of puncture is usually sufficient to stop the bleeding.)
Hematoma, seen in about 2% of patients, which manifests as bruises. These usually go away after a few days.
Dizziness, seen in about 1% of patients. Some patients have a conscious or unconscious fear of needles which can produce dizziness and other symptoms of anxiety. Patients are usually treated lying down in order to reduce likelihood of fainting.
The survey concluded: "Acupuncture has adverse effects, like any therapeutic approach. If it is used according to established safety rules and carefully at appropriate anatomic regions, it is a safe treatment method."

Rare, but major adverse events
Accupuncture and the vagus nerve
Though rare, if an accupuncture needle comes into contact with the vagus nerve, that contact can cause the heart rate to drop. This can, in effect, produce a seizure which requires immediate medical attention. One well documented and witnessed account occured at a meeting of the Mountain Home, Arkansas Rotary Club where approximately 100 attendees witnessed a Rotary member collapse after an accupuncture demonstration. The later explanation was that the needle had come into contact with the vegus nerve, which is, allegedly, a rare occurence.

Infection from reused needles
Infection is an important, and avoidable, risk that may arise due to use of unsterile or re-used needles. Reused needles can transfer blood-borne diseases such as HIV and hepatitis. To address this risk, the use of sterile, single-use-only needles is mandated by law in some countries, including the United States.

Use of sterile needles is also mandated in parts of Australia (cf. above), but poorly enforced. In New South Wales, basic health risks have been recently reported:


Environmental Health Team leaders classified acupuncture as a high-risk area. Procedures like bloodletting were being performed in one council area using un-sterilised needles. Other breaches of a serious nature include the re-use of single use needles. and - - :''The evidence provided by City of Sydney Council concerning their results of their regular hygiene inspections convinced the Committee that the public would best be protected by leaving acupuncturists under local council jurisdiction until the profession as a whole has been upgraded to higher clinical and professional standards.
Other injury
Other risks of injury from the insertion of acupuncture needles include:


Nerve injury, resulting from the accidental puncture of any nerve.
Brain damage or stroke, which is possible with very deep needling at the base of the skull.
Pneumothorax from deep needling into the lung.
Kidney damage from deep needling in the low back.
Haemopericardium, or puncture of the protective membrane surrounding the heart, which may occur with needling over an occult sternal foramen (an undetectable hole in the breastbone which can occur in up to 10% of people).
Risk of terminating pregnancy with the use of certain acupuncture points that have been shown to stimulate the production of adrenocorticotropic hormone (ACTH) and oxytocin.
These risks can all be avoided through proper training of acupuncturists. Graduates of medical schools and (in the US) accreditated acupuncture schools receive thorough instruction in proper technique so as to avoid these events. (Cf. Cheng, 1987)

Risks from omitting orthodox medical care
Some doctors believe that receiving any form of alternative medical care without also receiving orthodox western medical care is inherently risky, since undiagnosed disease may go untreated and could worsen. For this reason many acupuncturists and doctors prefer to consider acupuncture a complementary therapy rather than an alternative therapy.

Critics also express concern that unethical or naive practitioners may induce patients to exhaust financial resources by pursuing ineffective treatment.

Safety compared to other treatments
Commenting on the relative safety of acupuncture compared to other treatments, the NIH consensus panel stated that "(a)dverse side effects of acupuncture are extremely low and often lower than conventional treatments." They also stated:

"the incidence of adverse effects is substantially lower than that of many drugs or other accepted medical procedures used for the same condition. For example, musculoskeletal conditions, such as fibromyalgia, myofascial pain, and tennis elbow... are conditions for which acupuncture may be beneficial. These painful conditions are often treated with, among other things, anti-inflammatory medications (aspirin, ibuprofen, etc.) or with steroid injections. Both medical interventions have a potential for deleterious side effects but are still widely used and are considered acceptable treatments."
In a Japanese survey of 55,291 acupuncture treatments given over five years by 73 acupuncturists, 99.8% of them were performed with no significant minor adverse effects and zero major adverse incidents (Hitoshi Yamashita, Bac, Hiroshi Tsukayama, BA, Yasuo Tanno, MD, PhD. Kazushi Nishijo, PhD, JAMA). Two combined studies in the UK of 66,229 acupuncture treatments yielded only 134 minor adverse events. (British Medical Journal 2001 Sep 1). The total of 121,520 treatments with acupuncture therapy were given with no major adverse incidents (for comparison, a single such event would have indicated a 0.002% incidence).

This is in comparison to 2,216,000 serious adverse drug reactions that occurred in hospitals 1994. (Lazarou J, Pomeranz BH, Corey PN., JAMA. 1998 Apr 15;279(15):1200-5.) So to comapre directly, Acupuncture has a 0.02% chance of causing a minor adverse effect compared to prescription medications (Conventional medicine's treatment of choice) having a 6.7% chance of causing a serious adverse event in a hospital setting.

Legal and political status
Acupuncturists may also practice herbal medicine or tui na, or may be medical acupuncturists, who are trained in allopathic medicine but also practice acupuncture in a simplified form. License is regulated by the state or province in many countries, and often requires passage of a board exam.

United States
In the United States, acupuncturists are generally referred to by the professional title "Licensed Acupuncturist", abbreviated "L.Ac.". The abbreviation "Dipl. Ac." stands for "Diplomate of Acupuncture" and signifies that the holder is board-certified by the National Certification Commission for Acupuncture and Oriental Medicine Professional degrees are usually at the level of a Master's degree and include "M.Ac." (Master's in Acupuncture), "M.S.Ac." (Master's of Science in Acupuncture), "M.S.O.M" (Master's of Science in Oriental Medicine), and "M.A.O.M." (Master's of Acupuncture and Oriental Medicine). "O.M.D." signifies Doctor of Oriental Medicine, and "C.M.D." signifies Doctor in Chinese Medicine (zhong Yi,中医); these titles may be used by graduates of Chinese medical schools, or by American graduates of certain postgraduate programs. The O.M.D. and C.M.D. are not recognized by the Accreditation Commission for Acupuncture and Oriental Medicine (ACAOM), which accredits American educational programs in acupuncture. However, the O.M.D. (Doctor of Oriental Medicine) and D.O.M. (Doctor of Oriental Medine) degrees have been approved by some states. Each state regulates the practice of acupuncture within its territory. The ACAOM is currently beginning the process of accrediting the "Doctor of Acupuncture and Oriental Medicine" (DAOM) degree, and this new degree will represent the terminal degree in the field. The Oregon College of Oriental Medicine and Bastyr University were the first two institutions in the United States to offer the DAOM, and it is estimated that within the next ten years the DAOM degree will replace all master's level training programs in the United States.

In the USA, acupuncture is practiced by a variety of healthcare providers. Practitioners who specialize in Acupuncture and Oriental Medicine are usually referred to as "licensed acupuncturists", or L.Ac.'s. Other healthcare providers such as physicians, dentists and chiropractors sometimes also practice acupuncture, though they may often receive less training than L.Ac.'s. L.Ac.'s generally receive from 2500 to 4000 hours of training in Chinese medical theory, acupuncture, and basic biosciences. Some also receive training in Chinese herbology and/or bodywork. The amount of training required for healthcare providers who are not L.Ac.'s varies from none to a few hundred hours, and in Hawaii the practice of acupuncture requires full training as a licensed acupuncturist. The National Certification Commission for Acupuncture and Oriental Medicine tests practitioners to ensure they are knowledgeable about Chinese medicine and appropriate sterile technique. Many states require this test for licensing, but each state has its own laws and requirements. In some states, acupuncturists are required to work with an M.D. in a subservient relationship, even if the M.D. has no training in acupuncture.

Acupuncture is becoming accepted by the general public and by doctors. Over fifteen million Americans tried acupuncture in 1994. A poll of American doctors in 2005 showed that 60% believe acupuncture was at least somewhat effective, with the percentage increasing to 75% if acupuncture is considered as a complement to conventional treatment

In 1996, the Food and Drug Administration changed the status of acupuncture needles from Class III to Class II medical devices, meaning that needles are regarded as safe and effective when used appropriately by licensed practitioners

Canada
In the province of British Columbia the TCM practitioners and Acupuncturists Bylaws were approved by the provincial government on April 12, 2001. The governing body, College of Traditional Chinese Medicine Practitioners and Acupuncturists of British Columbia provides professional licensing. Acupuncturists began lobbying the B.C. government in the 1970s for regulation of the profession which was achieved in 2003.

In Ontario, the practice of acupuncture is now regulated by the Traditional Chinese Medicine Act, 2006, S.o. 2006, chapter 27. The government is in the process of establishing a College whose mandate will be to oversee the implementation of policies and regulations relating to the profession. Practitioners of Traditional Chinese medicine will be permitted to use the title 'Doctor of Traditional Chinese medicine'. In addition, they will be permitted to communicate a diagnosis to patients based on Traditional Chinese medicine techniques for diagnosis. However other regulated Health Care Professionals, such as naturopaths, physicians, physiotherapists, chiropractors, dentists, or massage therapists can perform acupuncture treatment when they fulfill educational requirements set up by their regulatory colleges.

United Kingdom
In the United Kingdom, British Acupuncture Council (BAcC) members observe the Code of Safe Practice with standards of hygiene and sterilisation of equipment. Members use single-use pre-sterilised disposable needles. Similar standards apply in most jurisdictions in the United States and Australia.

Acupuncture is also practiced by a number of registered medical practitioners, many of whom belong to the British Medical Acupunture Society, (BMAS)which also publishes a quarterly journal "Acupuncture in Medicine". Medical practitioners of Acupuncture in the UK vary in the degree to which they take account of traditional concepts like meridians, some thinking them to be very useful whilst others tend to concentrate on palpable "trigger points". Other acupuncture groups are The British Academy of Western Medical Acupuncture, (BAWMA) - nurses trained in acupuncture, The Acupuncture Acssociation of Chartered Physiotherpists, (AACP) and qualified ear acupuncturists trained either in restricted practice NADA and SMART or full ear acupuncture EAR and SAA.

Australia
In Australia, the legalities of practicing acupuncture also vary by state. In 2000, an independent government agency was established to oversee the practice of Chinese Herbal Medicine and Acupuncture in the state of Victoria. The Chinese Medicine Registration Board of Victoria aims to protect the public, ensuring that only appropriately experienced or qualified practitioners are registered to practice Chinese Medicine. The legislation put in place stipulates that only practitioners who are state registered may use the following titles: Acupuncture, Chinese Medicine, Chinese Herbal Medicine, Registered Acupuncturist, Registered Chinese Medicine Practitioner, and Registered Chinese Herbal Medicine Practitioner.

The Parliamentary Committee on the Health Care Complaints Commission in the Australian state of New South Wales commissioned a report investigating Traditional Chinese medicine practice. They recommended the introduction of a government appointed registration board that would regulate the profession by restricting use of the titles "acupuncturist", "Chinese herbal medicine practitioner" and "Chinese medicine practitioner". The aim of registration is to protect the public from the risks of acupuncture by ensuring a high baseline level of competency and education of registered acupuncturists, enforcing guidelines regarding continuing professional education and investigating complaints of practitioner conduct. The registration board will hold more power than local councils in respect to enforcing compliance with legal requirements and investigating and punishing misconduct. Victoria is the only state of Australia with an operational registration board. Currently acupuncturists in NSW are bound by the guidelines in the Public Health (Skin Penetration) Regulation 2000 which is enforced at local council level. Other states of Australia have their own skin penetration acts. The act describes explicitly that single-use disposable needles should be used wherever possible, and that a needle labelled as "single-use" should be disposed of in a sharps container and never reused. Any other type of needle that penetrates the skin should be appropriately sterilised (by autoclave) before reuse.

Many other countries do not license acupuncturists or require them be trained.

Feng shui


Feng shui, pronounced in English as [fʊŋ'ʃweɪ] ("fung shway") or [fɛŋ'ʃuːi] ("feng shoo-ee"), is the ancient Chinese practice of placement and arrangement of space to achieve harmony with the environment. The literal translation is "wind and water".
Feng shui involves the use of geographical, psychological, philosophical, mathematical, aesthetic, and astrological concepts in relation to space and energy flow. It is not simply a decorating style, but a discipline with guidelines compatible with many different techniques of architectural planning.
The source of the term is purported to come from the Burial Book written by Guo Pu (郭璞) in the Jin Dynasty (晉朝). Qi(氣), the energy of the universe, is carried in the wind and retained within water. Both elements were used as a way of directing Qi, thus giving feng shui its name. Wind is said to carry energy or Qi and therefore represents the principle of change and transformation in nature. Water is said to hold energy and therefore represents the principle of stability. When applied to human affairs, wind is also representative of action, fervor, and enthusiasm, whereas water is representative of internal strength, meditative qualities, and psychological power. By relating the holding and dispersing qualities of water and wind in nature to those in human behavior, feng shui also seeks to improve the human condition through the manipulation of physical space in a way that will impact on its corresponding qualities in humans.
An individual is usually not described as having bad or incorrect feng shui, but since the practice is linked to Qi, a persons energy can either deplete or add to the energy of his or her surroundings. The space can also effect the individual, especially in matters of luck, health, and prosperity. Feng shui is not only a practice that is related to physical space, but also to the inhabitors of the space it self, as both are interconnected.
History

It is generally believed that Qin fire had all feng shui books burned. The most authoritative work is "Qing Nang Jing" given by Huang Shi Gong to Zhang Liang during the late Qin Dynasty. In the Tang Dynasty, Yang Yun Song and his disciples wrote several books that are considered the most authoritative work by all feng shui schools.
These books were written in cryptic language and knowledge primarily passed down through the oral tradition, but it was also believed to be intuitive and derivable from common sense and our feeling of what is natural. Eitel traces the origins of feng shui as a distinct belief system to Chu Hsi's writings and commentaries from the Song dynasty (1126-1278). Chu Hsi's thought greatly influenced Confucianism and became the foundation of feng shui. But, more broadly speaking, feng shui's roots go back to the origins of Chinese philosophy.
In the 19th century, the Chinese government regularly published almanacs containing all the charts, diagrams, and numerical data used in feng shui practice.
Early English-speaking settlers in China in the mid-19th century reportedly ran into difficulties sparked by feng shui. Much like modern landowners having problems with building codes, these settlers had trouble in construction and renovation because their proposals did not conform to feng shui principles. Further, when unwanted foreigners tried to purchase land, they would be directed to spots with topographies causing very bad feng shui.
Due to ignorance, early Western commentators on feng shui were often skeptical and derogatory. A typical one in 1885 wrote "if any one wishes to see to what a howling wilderness of erratic dogmatism the human mind can arrive, when speculation usurps the place of science, and theories are reverenced equally with facts, let him endeavour to fathom even the elementary principles of that abyss of insane vagaries, the science of Feng-Shui. Others noted that, while naive as a science, it is more accurate than some Western mythologies.
Some scholars have noted that the general guidelines of feng shui have been followed across times and cultures using different languages and with different justifications.
Doctrine
Qi (or Chi)
Underlying the practical guidelines of feng shui is a general theory of Nature. Nature is generally held to be a discrete entity that breathes qi (a kind of life force or spiritual energy). The details about the metaphysics of what Nature is, what qi is and does, and what breath consists of vary and conflict. It is not generally understood as physical, but it is neither meant to be metaphorical nor fictionalistic (the latter being the view that even though an entity is fictional, it is useful to talk as if it really exists). It is the virtual energy and force that flows all around.
Feng shui translates into English as Wind and Water. These are the two containers for Qi. Since life exists within either air or water, qi is said to be the life energy that flows within these two environments.
The goal of feng shui guidelines is to locate and orient dwellings, possessions, land and landscaping, etc., so as to be attuned with the flow of qi. Location is considered to be of far greater significance than orientation. This is in line with modern thinking, where the 3 principles of buying a piece of property are location, location and location.
Yin and Yang
Fundamental to feng shui is the idea that two basic principles underlie all matter and energy in the universe, namely yin and yang. These forces are opposites, but are not in opposition. Rather they are complementary and need each other to exist and flourish. The constantly changing interactions of yin and yang give rise to the infinite variety of patterns in life. The following table outlines the basic nature of each principle:

Yin Yang Yin Yang
North South Winter Summer
Earth Heaven Matter Spirit
Female Male Negative Positive
Dark Light Night Day
Cold Heat Wet Dry
Down Up Low High
Inner Outer Decaying Flourishing
Passive Active Receptive Creative
Soft Hard Weak Powerful
Retiring Advancing Lingering Hasty


The bagua - directions and elements

The bagua (or pa kua) of the Yi Ching (Book of Changes) is an octagonal diagram used in feng shui analysis. Each direction on the octagon (north, northeast, etc.) is associated with certain significant aspects. By mapping the bagua onto a home, village, cemetery, etc., information about correct orientation and placement can allegedly be gleaned. However, there are two very different versions of the bagua. The first is the early heaven bagua, which represents the sacred, unchanging universe, and is used to orient sacred spaces such as temples and graves. The second version is the later heaven bagua which is used for more everyday and pratical spaces, such as homes and offices, as it represents the changing universe. Both have similar aspects, as they are both comprised of the eight trigrams, or guas. The orientation of the guas, however, are different and represent different trigrams and elements.
The Trigrams are the foundation of the I Ching, the seminal text of Chinese wisdom, and represent qualities that are observable in Nature as well as in human behavior. Each trigram is keyed to a particular orientation in space and to a particular phase of change in nature. There are eight trigrams, which when combined as double trigrams (called hexagrams), form a set of 64 potential situations or conditions in nature and in life. The eight trigrams are:
Heaven - The Creative principle which contains the potential for all of manifestation.
Earth - The Receptive principle which contains the potential for physical manifestation.
Fire - The Clinging principle which contains the potential for achievement, clarity, and vitality.
Water - The Abysmal principle which contains the potential for adaptability, mystery, and danger.
Thunder - The Arousing principle which contains the initial impulse for all new things.
Lake - The Joyous principle which embodies rewards and endings.
Mountain - The Stillness principle which contains the potential for serenity and internal power.
Wind - The Penetrating principle which contains the power to achieve without effort.
Whereas the trigrams describe conditions in the world, their change in time is described by the Theory of the 5 Elements, also known as the Theory of 5 Transformations. In this view, each of these elements – wood, fire, earth, metal, and water - represent a particular state or condition in time. One didactic tool often used to describe the elements and their relationship to each other is to compare them to the different seasons. Consequently, the Theory of 5 Elements is also related to the rotation of the sun, its particular position at different points in time, and therefore to the point of the compass. The practical use of the five elements is based on the fact that it can be employed within the household in order to stabilize, increase or decrease the Qi energies of the different elements.
The 5 Elements are:
Water - This is the quiet, cool, condensed energy of winter. It represents pure potential, such as the life force in a seed.
Wood - This is the awakening, active energy of spring. It represents growth, such as a sapling.
Fire - This is the hot, vibrant energy of summer. It represents achievement and clarity, such as a fruit.
Earth - This is the settled, mature energy of harvest time. It represents the community partaking of the bounty of nature.
Metal - This is the condensing, hardening energy of fall. It represents a return to beginnings and an ordering of nature's components.
In order to understand the Bagua and its relationship to space, it is necessary to map out the position of these energies according to the early and later heaven sequences. The early heaven sequence describes the state of nature in full equilibrium, without change or transformation. It refers to the sacredness of reality outside of space and time.
The eight directions of the early heaven bagua are:
North - trigram earth - element earth
South - trigram heaven - element metal
East - trigram fire - element fire
West - trigram water - element water
Northwest - trigram mountain - element earth
Northeast - trigram thunder - element wood
Southwest - trigram wind - element wood
Southeast - trigram lake - element metal
The later heaven sequence refers to the transformational quality of reality and describes change in time. It refers to the profane world of ordinary existence: to home, work, and human activity.
The eight directions of the later heaven bagua are:
North - trigram water - element water
South - trigram fire - element fire
East - trigram thunder - element wood
West - trigram lake - element metal
Northwest - trigram heaven - element metal
Northeast - trigram mountain - element earth
Southwest - trigram earth - element earth
Southeast - trigram wind - element wood
The Qi coming from each direction has its own quality, and these qualities vary for the two baguas. The directions on the Early Heaven Bagua represent the following:
The North contains the Qi of the Earth, the Nurturing Principle, which represents the material foundation of the cosmos. Its energy is condensing, substantive, and feminine.
The South contains the Qi of Heaven, the Creative Principle, which acts as a template for all of manifestation. Its energy is vital, righteous, and masculine.
The East contains the Qi of Fire, the Clarity Principle, which sets in motion the patterns of change and transformation. Its energy is active, expansive, and inspiring.
The West contains the Qi of water, the Abysmal Principle, which receives into itself the patterns of resolution and decay. Its energy is condensed, still, and dangerous.
The Center is the primordial void from which all of existence springs forth. It is both timely and timeless, local and universal. It is the foundation for the Tao.
For the Later Heaven bagua, they are as follows:
From the North the qi is nurturing and mysterious. Its symbols are the Black Tortoise, (the animal of winter), and the moon. It is linked to the element water , which is diplomatic, intuitive and compliant.
From the South the qi is invigorating and lucky. Its symbols are the Red Phoenix, (the bird of summer and good fortune), and the sun. It is linked to the element fire , which is dynamic, restless and energetic.
From the East the qi is protective, kind and competitive. Its symbols are the Green (or Gold) Dragon,(the animal of spring), and thunder. It is linked to the element wood , which is warm, generous, and seeks to grow.
From the West the qi is unpredictable and disruptive. Its symbols are the White Tiger (the animal of autumn), and the lake. It is linked to the element metal , which is unyielding, forceful and self-reliant.
In the Center lies the element earth, which is at home with all the directions, and seeks to harmonise them. The element earth is patient, stable and prudent.
Each kind of qi seeks its opposite to achieve harmony, thus the active, hot qi of the south seeks the cool qi of the north to balance itself; and the wise qi of the east seeks excitment from the qi of the west, and so on.
An example of use of the bagua is -- the stove (kitchen) should not be placed in the north part of a house, as water extinguishes fire. This is only a rule of thumb, and there are many other considerations in locating a kitchen.
Guidelines

Internal:
When you are sitting at a desk, the entrance door should be in a clear line of sight, and you should have a view of as much of the room as possible.
When lying in bed, the entrance door should not be directly facing the soles of one's feet. In other words, the end of the bed should not be in line with the door.
Straight lines and sharp corners are to be avoided, and especially should not point where people tend to sit, stand, or sleep.
Avoid clutter.
Keep tops of tables simple. Avoid overdecorating tables with objects and clutter. Those objects represent piles of stress and bad luck you could/will be carrying. You should be able to sit at a table and have an open view in front of you.
Your stairs should never face the front door.
Some objects are believed to have the power of redirecting, reflecting, or shifting energy in a space. These include mirrors, crystals, windchimes, and pools of flowing or standing water.
External:
Roads to and from ancient towns were often curved and windy, an attempt to disorient and keep away evil spirits, who were believed to travel in straight lines.
Avoid building houses in front of cemeteries, hospitals, and mortuaries.
The most auspicious spaces for homes are lots located in streets shaped like a horseshoe.
In choosing homes in rural areas, with hills and mountains, pick the one that is on a sloping hill.
In choosing homes in urban area, its best to go for the ones that are on a flat terrain.
Square-shaped lots are optimal for chi flow.
Schools of feng shui
The Form school

Feng shui developed thousands of years ago in little villages of East Asia. It was called folk feng shui because each village had their own guidelines on how to use it. Their livelihoods were dependent on it. They studied the formations of the land and ways of the wind & water (feng shui translated means the way of Wind & Water) to determine the best sitting for their survival. Over time feng shui developed and was used by emperors to ensure their success.
The original Feng Shui Masters were hired by emperors to wage war. It is said that they had the power to manipulate the wind, water and fog to help the outcome of battles. Folklore has it that the Emperor was fearful that they would use their skills against him, so he ordered the Feng Shui Masters put to death.
Some of the feng shui Masters went into hiding in the Buddhist Monasteries in fear for their lives. Some of them hid in remote village or densely mountainous village. Some passed away without passing it to any students. A few managed to passed it to his very loyal student with good character. Some Monks were trained in the ways of feng shui.
This is the origin of feng shui and what is called form school feng shui. It addresses the energies of the roads, rivers, mountains and placement of structures in relationship to them. Its premises are based upon the forces of Mother Nature. Typically you will find that Form School is utilized by both the Black Hat School and the Compass school.
The Compass school

Compass School has its roots in the study of the 28 Constellations along the ecliptic of the sun. Ancient Chinese believed that everything in Heaven had a corresponding part on Earth. The 28 Constellation ring is one of the most important rings of the luopan. The 24 mountains ring is another essential ring. It is an elaboration of the Ba Gua dividing each of the eight directions into 3 parts known as Heaven Dragon, Earth Dragon and Man Dragon.
One technique employed is the use of the Local Space Chart, which was reproduced in a generic form through the use of the luopan or geomantic compass. This device helps to determine the directional alignment of buildings. True traditional Compass School is based on translations of ancient texts and concepts. One such concept is the reference to the five Chinese elements or phases. Wood, fire, earth, metal and water are not really elements in the western scientific sense but merely represent phases and movement of natural processes. Other properties are ascribed including temperature and rising/descending qualities.
There are two primary forms of feng shui that utilizes the luopan. The first is called the East and West Group method or 8 House (8 Mansion) method. This method examines the directional influence on the people and the building to determine how and where best to align oneself within the building.
A second application is to use the luopan to find the orientation, combined with a time aspect creates a detailed chart of the qi within the building. This method is also known as Xuan Kong feng shui. Xuan Kong is also called the Time and Space method. It is concerned with looking at the qi within the building and mapping the floorplan to determine the auspicious and inauspicious areas. Utilizing the five Chinese elements of wood, fire, earth, metal and water, feng shui practitioners can create a balance within the qi, similar to needles correcting the qi in accupuncture.
The Black Sect school

Black Sect is a recent development of feng shui in the West, led by Grandmaster Thomas Lin Yun Rinpoche. It is sometimes called Black Hat Sect Tantric Buddhist. Black Sect feng shui relies less on directional energies, horoscopes, and astrology, and instead focuses on the internal orientation and organization of the space. For instance, the Black Sect always orients the bagua in line with the space's entrance, rather than northwards.
Some in the West prefer Black Sect feng shui, preferring to dispense with the astrological aspects of feng shui and focusing greater emphasis on its psychological benefits. Traditional Chinese feng shui schools do not officially recognize the Black Hat Sect due to its failure to adhere to previously set principles.
Flying Star school
Flying Star school is a traditional Chinese feng shui technique which seeks to optimize the potental of a building or structure. It is based on the relationship between the timing of construction of a particular structure and its orientation in space. Flying Star makes use of San Yuan or Three Cycles, which are comprised of sixty years each. These are further subdivided into periods of 20 years, single years, months, days, and hours. During each cycle, a certain form of Qi becomes stronger than the rest. Consequently, spaces must be dealt with differently as the Qi changes and shifts from one moment to the next and from one sector of a building to another. Flying Star postulates that there are certain orientations in any given cycle or period that are better than others. When applied in new construction, Flying Star is used to determine optimal orientation. As time moves on, however, the Qi may begin to falter, requiring additional adjustments to balance internal potential within the structure.
By adjusting and shifting the energies within a space, one can renew the potential of that structure within the constraints posed by the quality of that particular time and orientation. This shifting of Qi helps to strengthen different aspects of life that benefit the people that inhabit the space. Through the use of the bagua, the eight trigrams, and five element theory, Flying Star takes into account environment as well as interior design as a way of optimizing a space.
Classical feng shui

Classical feng shui or Xuan Kung feng shui, as practiced in Asia and in the west today, is an amalgam of all of the traditional aspects of feng shui. This includes form school, compass school and flying star feng shui.
Use in burials

The effect of proper feng shui on the living is thought to carry over to the afterlife. In traditional feng shui belief, the feng shui of cemeteries affects the state of the dead spirits and, indirectly, their living descendants. Spirits of the buried were believed to remain at their gravesites or by the homes of their kin, and just as bad feng shui harms relaxation and ease of mind among the living, the spirits of people buried with bad feng shui will be anxious and restless, and therefore more likely to trouble the living. This reasoning led to careful feng shui planning of cemeteries. Conversely, desecrating the feng shui of the grave of an enemy's ancestor was thought to be a powerful weapon.
The straight lines and sharp corners should not point at a gravesite or at the cemetery generally, a smooth or gradual landscape is preferable to rocky or otherwise sharp terrain. Waterways should be visible from the gravesite, but not loose rocks or boulders, which can be hidden by trees or bamboo.
The use of early forms of feng shui or geomancy in picking burial sites can be traced back at least to The Book of Burial (c. 300 CE), written by Guo Pu of the Jin Dynasty.
Criticism

Many critics regard Feng Shui as a form of superstition. Eitel calls it "a conglomeration of rough guesses at nature, sublimated by fanciful play with puerile diagrams."
High fees charged by independent feng shui consultants and a lack of consistency in their advice have raised eyebrows among skeptics. This has led to accusations of fraud, and practitioners being called cult members or snake oil salesmen, by said skeptics. Penn & Teller did a special on their show Bullshit! that was highly critical of the independent consultants featured.
Use in the West

In recent decades many feng shui books have been published in English, often focusing on interior design, architecture, interior decorating, and landscape design. Audiences have reacted skeptically towards the purported benefits of crystals, wind chimes, table fountains, and mirrored balls, etc., on one's life, finances, and relationships. Often, these claims are dismissed as New Age, pseudoscience, relying on the placebo effect, or even outright fraud.
Others reject feng shui's justifications for its rules (movement of various energies, etc.), but believe that some of its more practical rules (such as not working with one's back to a door) are very useful.
It is unclear what relationship these Western interpretations of feng shui have to the Eastern tradition. Many traditional feng shui practitioners in Asia regard Western adaptations as inauthentic.
Successful US businessman Donald Trump and Britain's Prince Charles are held to have used feng shui.
The Los Angeles Times reported that News Corp., Coca-Cola, Proctor & Gamble, Hewlett-Packard and Ford Motors are also using feng shui.

Great Wall of China


The Great Wall of China (literally "long city wall") or is a series of stone and earthen fortifications in China, built between 5th century BC and the 17th century to protect the northern borders of the Chinese Empire during the rule of successive dynasties.
Several walls, referred to as the Great Wall of China, were built since the 5th century BC, the most famous being the one built between 220 BC and 200 BC by the first Emperor of China, Qin Shi Huang; this wall was located much further north than the current wall built during the Ming Dynasty, and little of it remains.
The Great Wall is the world's longest man-made structure, stretching over 6,352 km (3,948 miles) from Shanhai Pass in the east to Lop Nur in the west, along an arc that roughly delineates the southern edge of Inner Mongolia.
History
The Chinese were already familiar with the techniques of wall-building by time of the Spring and Autumn Period, which began around 8th century BC. During the Warring States Period from 5th century BC to 221 BC, the states of Qi, Yan and Zhao all constructed extensive fortifications to defend their own borders. Built to withstand the attack of small arms such as swords and spears, these walls were mostly made by stamping earth and gravel between board frames.
Qin Shi Huang conquered all opposing states and unified China in 221 BC, establishing the Qin Dynasty. Intending to impose centralized rule and prevent the resurgence of feudal lords, he ordered the destruction of the wall sections that divided his empire along the former state borders. To protect the empire against intrusions by the Xiongnu people from the north, he ordered the building of a new wall that connects the remaining fortifications along the empire's new northern frontier. Transporting the large quantity of materials required for construction was difficult, so builders always tried to use local resources. Stones from the mountains were used over mountain ranges, while rammed earth was used for construction in the plains. There are no surviving historical records indicating the exact length and course of the Qin Dynasty walls. Most of the ancient walls have eroded away over the centuries, and very few sections remain today.
The Great Wall concept was revived during the Ming Dynasty, following the Ming army's defeat by the Mongols in the Battle of Tumu in 1449. The Ming had failed to gain a clear upper-hand over the Mongols after successive battles, and the long-drawn conflict was taking a toll on the empire. The Ming adopted a new strategy to keep the Mongols out, by constructing walls along the northern border of China. Acknowledging the Mongol control established in the Ordos Desert, the wall followed the desert's southern edge instead of incorporating the bend of the Huang He.
Unlike the earlier Qin fortifications, the Ming construction was stronger and more elaborate due to the use of bricks and stone instead of rammed earth. As Mongol raids continued periodically over the years, the Ming devoted considerable resources to repair and reinforce the walls. The sections near the Ming capital of Beijing were especially strengthened.
Towards the end of the Ming Dynasty, the Great Wall helped defend the empire against the Manchu invasions that began around 1600. Under the military command of Yuan Chonghuan, the Ming army held off the Manchus at the heavily fortified Shanhai Pass, thus preventing the Manchus from entering the Liaodong Peninsula and the Chinese heartland. The Manchus were finally able to cross the Great Wall in 1644, when the gates of Shanhai Pass were opened by Wu Sangui, a rebel Ming border general. The Manchus quickly seized the Ming capital of Beijing, and subsequently defeated the remaining Ming resistance to establish the Qing Dynasty.
Construction and repairs of the Great Wall were discontinued under the Qing rule, as China's borders extended beyond the walls and Mongolia was annexed into the empire.
Notable areas
The following three sections are located in Beijing Province where reconstruction has taken place and which are regularily visited by modern tourists:
• The “North Pass” of Juyongguan pass, known as the Badaling. When used by the Chinese to protect their land, this wall was well-manned by guards so as to guard China’s capital, Beijing. Made out of stone and bricks from the hills, this portion of the Great Wall is 7.8 meters high and 5 meters wide.
• One of the most striking sights of the Ming Great Wall, is where the wall climbs extremely steep slopes. It runs 11 kilometers long, ranges from 5 to 8 meters in height, and 6 meters across the bottom, narrowing up to 5 meters across the top. Wangjinglou is one of Jinshanling's 67 watchtowers, rising 980 meters above sea level.
• South East of Jinshanling, is the Mutianyu Great Wall which winds along lofty, cragged mountains from the southeast to the northwest for approximately 2.25 kilometers (about 1.3 miles). It is connected with Juyongguan Pass to the west and Gubeikou to the east.
Another notable section lies near the eastern extremity of the wall where the first pass of the Great Wall was located on the Shanhaiguan (known as the “Number One Pass Under Heaven”), the first mountain the Great Wall climbs. Jia Shan, is also located here, as is the Jiumenkou, which is the only portion of the wall that was built as a bridge. Shanhaiguan Great Wall is referred to as the “Museum of the Construction of the Great Wall”, because of a temple, the Meng Jiang-Nu Temple, built during the Song Dynasty.
Characteristics

Before the use of bricks, the Great Wall was mainly built from earth, stones and wood.
Bricks were heavily used in many areas of the wall during the Ming Dynasty, as well as materials such as tiles, lime, and stone. Bricks were easier to work with than earth and stone as their small size and light weight made them convenient to carry and augmented construction speed. Additionally, they could bear more weight and retain their integrity better than rammed earth. Stone, though more difficult to use, can better hold well under its own weight than brick. Consequently, stones cut in rectangular shapes were used for the foundation, inner and outer brims, and gateways of the wall.
The steps that form the Great Wall of China are very steep and tall in some areas of the wall. Tourists often become exhausted climbing the wall and traverse no more than a mile because of this reason. Along the wall on either side, are “holes” where the builders of the Great Wall didn’t place any bricks. They are a little over a foot tall, and about 9 inches in width. These holes were used to shoot arrows out of when being attacked.
Condition

While some portions near tourist centers have been preserved and even reconstructed, in many locations the Wall is in disrepair, serving as a playground for some villages and a source of stones to rebuild houses and roads. Sections of the Wall are also prone to graffiti and vandalism. Parts have been destroyed because the Wall is in the way of construction sites. Intact or repaired portions of the Wall near developed tourist areas are often plagued with hawkers of tourist kitsch.
After one of the many runs for charity along the Great Wall, H.J.P Arnold questioned several runners about the status of the wall. A typical response was "The wall was clearly discernible and only moderately eroded along 22% of the run. The Wall was usually discernible but frequently broken/eroded 41% of the run, and scarcely discernible and almost totally eroded 37% of the run"
Watchtowers and barracks

The wall also has watch towers at regular intervals, which were used to store weapons, house troops, and send smoke signals. Barracks and administrative centers are located at larger intervals.
Communication between the army units along the length of the Great Wall, including the ability to call reinforcements and warn garrisons of enemy movements, was of high importance. Signal towers were built upon hill tops or other high points along the wall for their visibility.
Recognition

The Wall was made a UNESCO World Heritage Site in 1987.
Mao Zedong had a saying, "You're not a real man if you haven't climbed the Great Wall". Originally this saying was used to bolster his revolution in trekking north. But due to the erosion of time the saying has been reduced to a promotional slogan for the Great Wall of China. In Badaling (north of Beijing) the 'real man stone' can be found with the saying engraved in it.
From outer space

Ripley's Believe It or Not! cartoon from May 1932 makes the claim that the wall is "the mightiest work of man, the only one that would be visible to the human eye from the moon" and Richard Halliburton's 1938 book Second Book of Marvels makes a similar claim. This belief has persisted, assuming urban legend status, sometimes even entering school textbooks. Arthur Waldron, author of the most authoritative history of the Great Wall, has speculated that the belief might go back to the fascination with the "canals" once believed to exist on Mars. (The logic was simple: If people on Earth can see the Martians' canals, the Martians might be able to see the Great Wall.)
The Great Wall is a maximum 30 feet wide and is about the same color as the soil surrounding it. Based on the optics of resolving power (distance versus the width of the iris: a few millimetres for the human eye, metres for large telescopes) an object of reasonable contrast to its surroundings some four thousand miles in diameter (such as the Australian land mass) would be visible to the unaided eye from the moon. But the Great Wall is of course not a disc but more like a thread, and a thread a foot long would not be visible from a hundred yards away, even though a human head is. Not surprisingly, no lunar astronaunt has ever claimed he could see the Great Wall from the moon.
A different question is whether it is visible form near-Earth orbit i.e at an altiude of less than 500 km - 0.1% of the distance of the moon. The consensus here is that it is barely visible, and only under nearly perfect conditions; it is no more conspicuous than many other manmade objects.
Astronaut William Pogue thought he had seen it from Skylab but discovered he was actually looking at the Grand Canal of China near Beijing. He spotted the Great Wall with binoculars, but said that "it wasn't visible to the unaided eye." US Senator Jake Garn claimed to be able to see the Great Wall with the naked eye from a space shuttle orbit in the early 1980s, but his claim has been disputed by several US astronauts. Chinese astronaut Yang Liwei said he could not see it at all.
Veteran US astronaut Gene Cernan has stated: "At Earth orbit of 160 km to 320 km high, the Great Wall of China is, indeed, visible to the naked eye." Ed Lu, Expedition 7 Science Officer aboard the International Space Station, adds that, "it's less visible than a lot of other objects. And you have to know where to look."
Neil Armstrong stated about the view from Apollo 11: "I do not believe that, at least with my eyes, there would be any man-made object that I could see. I have not yet found somebody who has told me they've seen the Wall of China from Earth orbit. ... I've asked various people, particularly Shuttle guys, that have been many orbits around China in the daytime, and the ones I've talked to didn't see it."
Leroy Chiao, a Chinese-American astronaut, took a photograph from the International Space Station that shows the wall. It was so indistinct that the photographer was not certain he had actually captured it. Based on the photograph, the state-run China Daily newspaper concluded that the Great Wall can be seen from space with the naked eye, under favorable viewing conditions, if one knows exactly where to look
These inconsistent results suggest the visibility of the Great Wall from near earth orbit depends greatly on the seeing conditions, and also the direction of the light (oblique lighting widens the shadow). Features on the moon that are dramatically visible at times can be undetectable at other times due to changes in lighting direction; the same would be true of the Great Wall.

Quick View To Civilization Of Chinese Food







It is not easy to brief the civilization of Chinese Food in a short message, it is because, there are more than 56 folks inside the Mainland China, and the large area causes difference dining habits among the difference districts.

Because of their farming products, the people living in Southern China will have rice, congee or rice noodle as their main food, and who will have wheat made products like Bun, noodle, pancake in Northern China. The populace who living on seaside and lakeside will have seafood or lake fishes as meals. Of course, people can have any food as they want nowaday.










Guangdong Style Rice CongeeShanghai Style Pork Buns


Taste Depends On Climate
There is a big difference about the diets between Northern and Southern China, that is, the dishes made by Northern Chefs are in heavier taste and those are comparably light in Southern Chefs’ recipes, sometimes, we say it is tasty as sweet and fresh in Southern Chinese food. In the Northern and Western Provinces of China like Lingxia, hebei, Sichuan , Shenxi, and Yunnan, the diets are made in hot and spicy, because of the humid cold weather and high altitude, Chinese people wonder that to perspire is a good method for preventing diseases caused by humidity and cold.


 


Herds And Spices, Preserved Materials
There are not popular to use herds and spices in Chinese Food, perhaps Chinese chefs will use some parsley, aniseed, fennel, cloves, Sichuan peppercorn, red chili pasty……however, they mostly use light and dark soy sauce, Shaoxing wine, rice vinegar and oyster sauce as the main seasoning and sauce. Chinese chefs usually like to use the preserved and salty
Ingredients like preserved eggs, potherb and pickled mustard, dried shrimps, bean curd cheese, dry and salty pork, salty duck, meat sausage……it is a long and traditional habit since the ancient hard and poor farming society.

Peking Man


About Peking Man


Peking Man (sometimes now called Beijing Man), also called Sinanthropus pekinensis (currently Homo erectus pekinensis), is an example of Homo erectus.
The remains were first discovered in 1923-27 during excavations at Zhoukoudian (Choukoutien) near Beijing (Peking), China. The finds have been dated from roughly 250,000-400,000 years ago in the Pleistocene.


Original fossils

This fossil was originally found by Birgir Bohlin only 3 days before work was to be stopped.
First studies began at Zhoukoudian in 1921 with an investigation of a number of caves in the limestone there. According to later accounts of Otto Zdansky, who was working for geologist Johan Gunnar Andersson, a local man lead western archaeologists to what is today known as the Dragon Bone Hill, a place full of fossilized bones. Zdansky began his own excavation and eventually found bones that resembled human molars. In 1926, he took them to the Peking Union Medical College, in Peking, where Canadian anatomist Davidson Black analysed them. He later published his finds in the journal Nature.
The first specimens of Homo erectus had been found in Java in 1891 by Eugene Dubois, with the Java Man initially being named Pithecanthropus erectus but later transferred to the genus Homo.
The Rockefeller Foundation agreed to fund the work at Zhoukoudian. By 1929, Chinese archaeologists Yang Zhongjian and Pei Wenzhong, and later Jia Lanpo, had taken over the excavation. Over the next seven years, they uncovered fossils of more than 40 specimens including 6 nearly complete skullcaps. Pierre Teilhard de Chardin and Franz Weidenreich were also involved.
Excavation ended in July 1937 when the Japanese occupied Beijing. Fossils of the Peking Man were placed in the safe at the Cenozoic Laboratory of the Peking Union Medical College. Eventually, in November 1941, secretary Hu Chengzi packed up the fossils so they could be sent to USA for safekeeping until the end of the war. They vanished en route to the port city of Qinghuangdao. They were probably in possession of a group of US marines who the Japanese captured when the war began between Japan and USA.
Various parties have tried to locate the fossils but, so far, without result. In 1972, a US financier Christopher Janus promised a $5,000 (U.S.) reward for the missing skulls; one woman contacted him, asking for $500,000 (U.S.) but she later vanished. Janus was later indicted for embezzlement. In July 2005, the Chinese government founded a committee to find the bones to coincide with the 60th anniversary of the end of World War II.
There are also various theories of what might have happened, including a theory that the bones had sunk with a Japanese ship Awa Maru in 1945.
The Peking Man Site at Zhoukoudian was listed by UNESCO as a World Heritage Site in 1987.


Paleontological conclusions


Because all the pre-war findings at Zhoukoudian were lost during transit to the USA, subsequent researchers have had to rely on casts and existing writings from the original discoverers.
Contiguous findings of animal remains and evidence of fire and tool usage, as well as the manufacturing of tools, were used to support H. erectus being the first "faber" or tool-worker. The analysis of the remains of "Peking Man" led to the claim that the Zhoukoudian and Java fossils were examples of the same broad stage of human evolution. This is also the official view of the Chinese Communist Party.
This interpretation was challenged in 1985 by Lewis Binford, who claimed that the Peking Man was a scavenger, not a hunter. The 1998 team of Steve Weiner of the Weizmann Institute of Science concluded that they had not found evidence that the Peking Man had used fire.
