Five elements, also known as the theory of five elements, is the basic way to understand the world. The meaning of the five elements includes five basic trends in the evolution of Yin and Yang: gold (convergence), wood (growth), water (infiltration), fire (disillusionment) and earth (integration). 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 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.
