It is not because Chinese medicine is unscientific and not advanced, but that different fields and levels need different mathematical expressions. For example, everything in chemistry can be deduced by quantum theory, but that is too complicated, so chemistry has its own set. In fact, TCM has its own mathematical foundation, which is China's theory of Yin and Yang. It can be seen that the premise of mathematization of TCM is the mathematization of Yin-Yang theory.

As a natural subject in ancient China, the theoretical core of TCM is of course inseparable from the theory of Yin and Yang. Chinese medicine believes that "Yin Pingyang is the secret and God is the rule"; "Yin and Yang are separated, essence and qi are separated", that is to say, when Yin and Yang are balanced, the body will be healthy. When yin and yang are out of balance, the body will be sick and the separation of yin and yang will end. Therefore, the basic principle of treating diseases in traditional Chinese medicine is to regulate yin and yang and restore the balance of yin and yang. All treatment methods are specific methods to restore the balance of yin and yang.
