Why should the theory of Yin and Yang also use Jin Mu's theory of water, earth, fire and dirty!

Yin-yang theory is a simple materialistic dialectical thought established by the working people in ancient China by observing various things and phenomena and dividing everything in the universe into Yin and Yang. According to the theory of Yin and Yang, the formation, change and development of everything lies in the movement of Yin and Yang. It sums up the law of the change of Yin and Yang in nature and accords with the philosophy of unity of opposites. The theory of Yin and Yang is not only applied to various scientific fields, but also to traditional Chinese medicine, which has become the theoretical basis of China's natural science and materialistic world. The theory of five elements is also the original creation of our people. The essence of the Five Elements Theory is that the world consists of five basic substances: wood, fire, earth, gold and water, and the development and changes of various things and phenomena in nature are the result of the constant movement and interaction of these five different substances. This discovery clarified the laws and causes of the birth, aging, illness and death of all things in the universe. The theory of yin-yang and five elements is of great significance in the fields of science and traditional Chinese medicine!
