It is said that this kind of golden bell jar, iron cloth shirt kung fu, unless practiced to the peak of the Mahayana realm, otherwise every person who practices has a fatal acupoint, which is also the place where his body breath communicates with the outside world, if this acupoint is restrained by the other party, it is very likely to make all the meridians in the body disordered in an instant, and then evolve into a madness, at that time, not only can he not control himself, it is very likely to become a neurosis, so Itahara Chong began to consciously explore the other party's acupoint.

It is important to know that in fact, the acupuncture points of the human body refer to the special points on the meridian line of the human body, and Chinese medicine can stimulate the corresponding meridian points through acupuncture or massage, tapping, and moxa to treat diseases. Acupuncture points are a unique term in the culture of country Z and traditional Chinese medicine. It is mostly where there are few nerve endings and blood vessels. It is also called acupuncture and acupuncture.

Acupuncture point is the highest potential of human and animal subcutaneous electric field area, is the nerve trunk and nerve endings through the place, is the human and animal body in the highest potential energy of the place, this part of the destruction or necrosis, as well as external force damage and obstruction, will cause numbness, swelling, itching, pain, sour and other symptoms, and even produce tissues, organs, circulation and heart and brain discomfort, can also lead to disability, failure, suffocation and death and other symptoms, acupoints are the most important electric field, but also with the brain close contact place.

Some people have discussed the electrical characteristics of acupuncture points and found that there are "good conductive points" in some places on the skin with particularly high electrical conductivity, and their positions coincide with the positions of acupuncture points. But later it was found that the total area of acupuncture points in the whole body was only 4/10,000 of the body surface, and the resistance parts were much more. Later, people used the weakest current to stimulate the muscles, and the place where the muscles can produce the maximum contraction effect is called the exercise point. After control, it was found that the distribution of movement points and acupuncture points was almost the same. But what the mechanism of the point of motion is, it is not well understood.

Someone else studied the relationship between acupuncture points and nerves, and found that almost all acupuncture points are associated with nerves. A certain acupuncture point and the nerves of a certain organ often belong to the same spinal cord segment. During embryonic development, the skin and nerves are homologous, and the nerve center has projection points for various skin regions and organs. However, the contrary opinion is that there is also a distribution of nerves in the non-acupuncture point area, and there is no histological difference between them. Some people also found that acupuncture points are closely related to blood vessels and lymphatic vessels, and the skin temperature at acupuncture points is higher than that in other places, which may be because of this series of complex relationships to form the mystery of acupuncture points.

Many people explore the essence of acupuncture points in terms of their electrical properties.

In 1950, Nakatani of country R used 12 volts of direct current to pass through human skin, and found that there were some "good conduction points" on the skin with particularly high electrical conductivity, and their positions coincided with the position of acupuncture points. Shortly thereafter, the famous French acupuncturist Nibearte, with the assistance of his assistant, confirmed this phenomenon by applying the method of measuring the skin resistance, and determined that the resistance of the acupuncture point was only half of the resistance of the skin around it. The same results were obtained for measurements taken on cadavers.

In the late 50s of the 20th century, scholars from country Z studied the electrophysiology of acupuncture points, and basically affirmed that acupuncture points have the characteristics of low resistance and high potential. However, it is speculated that the total area of acupuncture points in the whole body accounts for only 4/10,000 of the body surface, while there are many parts of the resistance on the whole body surface, which are far from being limited to the acupuncture points. In addition, physiological activities such as eating, sleeping, and exercising, changes in the external environment such as timing, season, and temperature, as well as many factors such as mental state, will affect the skin resistance value. It is no wonder that researchers from the Shanghai Institute of Hypertension lamented that it is quite difficult to determine meridian points with this (skin resistance measurement).

It took five years for F-country Della Fuye to apply this method to determine acupuncture points, but the results obtained were very different from those of Z-country acupuncture points, and he had to abruptly stop the study. There are also people who compare and analyze the ancient theory of acupoints with modern medical theories, and try to explain them with new theories and concepts. For example, when an electric current stimulates the skin, the stimulated muscles contract. After comparing the position of the exercise point with the position of the traditional acupuncture point, the Chinese scholar Jin Lin proposed that the distribution of the two is almost the same.

The head of the soldier in country R, Justice, and Frost and others in country M compared the acupuncture points with the trigger points. The trigger point is considered to be a local intersecting site in the body's musculature, which is characterized by deep tissue sensitivity, nodules, and radiating pain. Although the mechanism of its production is unknown, it is thought to be caused by pain or other causes of muscle spasms, endocrine disorders, or muscle tension. Acupuncture points can cause damage to muscle fibers and nerve fibers in local tissues due to the friction between tissues and the interaction between metal needles and tissue dielectrics.

In addition, the distribution of the two is slightly the same. As a result, they believe that some of the properties of acupuncture points are very similar to trigger points. Some even think that they are nothing more than synonyms. There are also studies that report that acupuncture points are closely related to differential electric points and skin activity points. These multi-channel studies reflect the characteristics of acupuncture points from the side, and undoubtedly have certain reference value for exploring the mystery of acupuncture points.

Some people also focus on studying the morphological structure of acupuncture points, hoping to unravel the mystery of acupuncture points in one fell swoop. Experts from the First Medical College of Shanghai in Z dissected and observed 324 acupuncture points on the corpse and found that 99.6% of the acupuncture points were related to nerves. They further found that the nerve distribution of meridian points and related organs often belong to the same spinal cord segment, and Chinese scholar Hidetaro Mori proved that in the acupuncture points of the whole body, about 100 acupuncture points deeply penetrate the nerve bundles. Acupuncture points are also associated with receptors at the end of the process around sensory ganglion cells, such as muscle spindles, nerve tendon spindles, tactile bodies, and annular stratosomes. From a genetic point of view, the epidermis and nervous tissue share a common origin. The nerve center has projection points for various skin areas and internal organs. Therefore, there may be a biogenesis correlation between acupuncture points and embryonic morphology.

However, there are also studies that have come to the opposite conclusion: there is a distribution of nerve fibers in both acupuncture and non-acupuncture point tissues, and there is no significant difference in histology between them. As for the difference between the acupuncture points and the non-acupuncture point areas of the lower nerve tissue, it is still unclear. It has also been reported that the skin temperature in the acupuncture points and blood vessels and Honsaijo Ichijo applied infrared thermal imaging to observe that the skin temperature in the chest and abdomen acupoint area is 0.5 to 1C higher than that of the surrounding skin, which he believes is due to the presence of blood vessels under the acupuncture points. The anatomical data confirmed that many of the acupuncture points were indeed covered with subcutaneous veins or penetrated by deep blood vessels.
