Meridian is the channel through which qi and blood run in human body, which belongs to zang-fu organs internally and distributes all over the body externally, connecting various tissues and organs into an organic whole. Meridian refers to the meridian, which is like a straight path and the backbone of the meridian system; Collaterals refer to collaterals, just like networks, which are tiny branches of meridians. Meridian is the general name of meridian.

During the period of 1957, Dr. Yoshio Nakatani, a professor of biology at Kyoto University in Japan, published the theory of activating collaterals and guiding meridians. 100, more than one medical expert made further research on the instrument of meridians and acupoints, and continued to collect data and clinical experiments. At present, a huge database of more than one million cases has been accumulated and supplied to the inspection system to infer health status through statistical analysis. (This is just a statement of the theory of good collateral. Meridian detector has three origins, among which the theory of meridian detection was first put forward by the former Soviet Space Agency, which competed with the United States for all-round control of outer space. The health of astronauts also belongs to this category. At that time, it was found that the traditional western medicine detection method was influenced by various external factors such as cosmic ray weightlessness. It will lead to the difficulty and accuracy of the test. The former Soviet Union used its authoritarian political system and control over East Germany, a country with the most advanced research on meridian energy medicine, to study meridian energy medicine.

This research began in the1960s, until the disintegration of the former Soviet Union, Russian experts brought it to the East Berlin Science and Technology Expo, and this technology was purchased by Xu Zhan Electronics in Taiwan Province Province for further research. But Japanese doctors are limited by their own conditions. We can't do a lot of basic data research, but imitate it according to the theories of traditional Chinese medicine and energy medicine. It is impossible to have millions of case data. Because the collection of basic pathological data of meridian technology has strict requirements, it is not to say that a pathological case can be formed by one test. However, it is necessary for the subjects to repeat the test for a long time in strict accordance with the regulations in order to draw the conclusion that personal freedom needs to be restricted. At the same time, it also needs huge economic and material resources to carry out. It is very important that a doctor in a university can't collect so many basic cases.
