In Huangdi Neijing, the five elements and Yin and Yang are regarded as the source of life education. The theory of five elements is a theory of ancient human beings to study the movement and change law of natural qi, and an ancient natural science theory to study the origin and movement law of life. Five elements are one of the important contents of the basic theory of traditional Chinese medicine. According to the records of Huangdi Neijing and other ancient books, this paper discusses the basic concepts of the five elements from the movement mode of qi.

What are the movement forms and characteristics of Qi represented by the five elements? What is the basis for classifying all things in nature with the five elements? The ancients used the method of "looking up at the sky, overlooking geography, and knowing people in the middle" to study.

Five elements: wood, fire, earth, gold and water;

Five numbers: eight, seven, five, nine, six;

East, south, middle, west and north;

Because the theory of five elements was gradually formed in the long historical process, different viewpoints appeared in the process of its formation, and even different understandings appeared in the classification of nature and human organs with five elements, which is completely possible, objective and understandable.

What's more, it is also a historical fact that Taoism, Dan family, military strategist and Confucianism all reformed the theory of five elements according to the needs of their respective schools. The five elements theory of traditional Chinese medicine, like the theory of Yin and Yang, was originally a theory of ancient human beings to study the movement and change law of natural gas in heaven and earth, and an ancient natural science theory to study the origin and movement law of life. Chinese medicine prevents and treats diseases according to the laws of nature and life.
