Hao Wanshan said that what exactly are the five elements of health (7)?

The Five Elements is a systematic view of Taoism in China since ancient times, which is widely used in traditional Chinese medicine, geomantic omen, numerology, physiognomy and divination. The meaning of the five elements includes five basic trends in the evolution of Yin and Yang: water (moistening the lower part), fire (burning the upper part), gold (converging), wood (prolonging) and earth (neutralizing). Ancient philosophers in China used the theory of five elements to explain the formation of all things in the world and their relationships. It emphasizes the whole concept and aims to describe the movement form and transformation relationship of things. Yin and Yang are ancient theories of unity of opposites, and the five elements are primitive system theories.
