Yellow Emperor's Canon of Medicine is the earliest extant medical canon in China that records the achievements of medicine made by Chinese people in ancient times. In the Preface to Explanation of Yellow Emperor’s Canon of Medicine • Plain Conversation, Wang Bing, an important medical scholar in the Tang Dynasty (618 〜 907 A. D. )，said， “It is simple in description, profound in meaning, and mysterious in theory. It describes the difference between the heavens and the earth，the order of Yin and Yang, the causes of changes and the signs of life and death. ”In the past thousands of years, Yellow Emperor’s Canon of Medicine guided the development of TCM (traditional Chinese medicine) . The so-called various schools of theories in TCM developed in history all originated from the basic theory elucidated in Yellow Emperor's Canon of Medicine.
