Who can elaborate on China's Five Elements Theory? thank you

China's theory of Yin-Yang and Five Elements is a simple materialism and spontaneous dialectics in ancient China. It holds that the world is material, and the material world is nurtured, developed and changed under the impetus of Yin and Yang. People think that the five most basic substances, wood, fire, earth, gold and water, are indispensable elements in the world. These five substances depend on each other and are in constant movement and change. This theory had a far-reaching influence on the later ancient materialist philosophy. On the basis of long-term medical practice, the theory of Yin-Yang and Five Elements has been widely used in the medical field to explain the origin, physiological phenomena and pathological changes of human life, guide clinical diagnosis and prevention, become an important part of the theory of traditional Chinese medicine, and have a far-reaching impact on the formation and development of the theoretical system of traditional Chinese medicine.

The relationship between wood, fire, earth, gold and water is referred to as the five elements.

The basic meaning of the five elements refers to a basic pattern of contradictory interests, which can be summarized as "harmful to me, beneficial to me, beneficial to me, harmful to me", whether within things or between different things. Extract me from this model and express it with the image of soil, then the image harmful to soil is wood, the image beneficial to soil is fire, the image beneficial to soil is gold, and the image harmful to soil is water. It is not difficult to know that advantages or disadvantages are actually synonymous with mutual resistance. In reality, there is no interest that has nothing to do with this contradictory interest pattern, so the restraint mode expressed by the five elements belongs to the basic mode of contradictory interests within everything and between different things. Accordingly, it is not difficult for us to understand why the traditional explanation of the so-called five elements is a classification method, or that the five elements refer to the movement of five substances, namely wood, fire, earth, gold and water, and it is a simple cognitive method.
