People are born if they have qi, and die if they do not have it. Qi is the matrix of all life, and Yin and Yang are sympathetic to produce all things. “One Qi” believes that the same “Qi” penetrates all things in the world. “Huai nanzi” says that Tao begins with One, One can be divided into Yin and Yang, Yin and Yang are harmonious and everything is born. All things leave behind them the Obscurity (out of which they have come), and go forward to embrace the Brightness (into which they have emerged), while they are harmonised by the Breath of Vacancy. “Tao Te Ching”, which is the Taoism classic works of pre Qin, says that: 4 Tao produces One, the One produces Two (Yin and Yang), and the Two produces Three (Yin, Yang and the exchange between Yin and Yang), then the Three generates all things. Another Taoist classic, “Zhou Yi Shen Tong Qi”, uses hexagrams and lines to match the Yin and Yang and the Five Elements to lay the theoretical foundation of Taoist golden alchemy. In the “Classic of Great Peace”, an early Taoist classic, the thought of Yin-Yang and Five Elements was also absorbed, which was used to examine the nature of everything in the world and explain the truth of meditation. Yin and Yang theory and Five Elements theory are typical important philosophical thoughts in ancient China. 3 The Yi-ology expounds the dynamic and static changes of Yin and Yang in everything in the world. Its theoretical basis includes the theory of Yin and Yang and Five Elements, the principle of induction between human and nature, and the monism of Qi. Taoist medicine originated from the philosophical thoughts in the pre-Qin period, especially the Yi-ology thoughts and Taoist thoughts in the pre-Qin period. It is a diversified medical model integrating physiological therapy, belief therapy and psychotherapy. It is related to and different from Chinese traditional medicine, and its essence of medicine and pharmacology is an integral part of Chinese medicine. It includes taking medicine, external medicine, internal medicine, guiding technique (also named Dao Yin), elixir and spells with witch doctor color, etc. The definition of Taoist medicine in Encyclopedia of China Religious Volume is the following: Taoist medicine is the medical knowledge and technology accumulated by Taoism in the process of internal cultivation and external cultivation in pursuit of immortality, inheritance and absorption of Chinese traditional medical achievements. 1 Taoism has gradually formed a unique Taoist medicine in the long time and development process.

In the process of long-term development and melting, it not only inherits Taoist thoughts, but also includes various thoughts of Mohist, Military and Legalist.
