Mostly used in philosophy, traditional Chinese medicine and divination. The five elements refer to wood, fire, earth, gold and water. It is believed that nature consists of five elements, and with the rise and fall of these five elements, nature changes, which not only affects people's fate, but also makes everything in the universe circulate endlessly. The theory of five elements holds that everything in the universe is composed of the movement and change of five basic substances: wood, fire, soil, gold and water. It emphasizes the whole concept and describes the structural relationship and movement form of things. If Yin and Yang are an ancient theory of unity of opposites, the five elements can be said to be a primitive general system theory.
