Understanding that TCM has the characteristics of China traditional culture.

China's traditional thinking is based on perceptual thinking, while modern natural science is based on rational thinking. Traditional Chinese medicine should be the most rational subject in Chinese traditional studies, and it can definitely be called science. The Book of Changes, as a reference book for divination, is different from the natural science established by western mathematics and logic, although it carries ancient philosophical achievements and tries to explain all natural and social problems. Moreover, the Book of Changes we are talking about now is not the original work of 3,000 years ago. The theory of yin-yang and five elements developed in the pre-Qin period was added, which is the theoretical basis of traditional Chinese medicine. At the same time, traditional Chinese medicine has also changed from the initial empirical science to a rational science with rich theory and experience. Due to the inheritance of Chinese civilization, it is logical that the Book of Changes, which was first formed in China and contains rich philosophical thoughts, can guide the formation of the theory of Yin-Yang and Five Elements and the development of TCM theory. The same development discipline covers almost all fields of China's traditional studies, and gradually becomes the basic idea of China's traditional studies. China people also use all kinds of divination developed from pre-Qin divination. There are more than 30 kinds of divination commonly used, such as six hexagrams, four pillars, geomantic omen, strange gate, six nobles and astrology ... Of course, this is also related to the divination function of the Book of Changes itself, which also confuses people's views on the Book of Changes and future China.
