Five elements is a systematic view of ancient Taoist philosophy in China, which is widely used in traditional Chinese medicine, geomantic, fate and divination. The meaning of the five elements includes five basic trends in the evolution of Yin and Yang: water, fire, gold, wood and soil.
The theory of five elements is also a philosophical thought created by ancient Chinese people. It takes five substances in daily life: gold, wood, water, fire and earth as the basis for the changes of all things in the universe and various natural phenomena. These five kinds of substances have different attributes, such as wood growth and development; fire is hot and upward; soil is peaceful and realistic; gold is killing and convergence; water is cold and moist. The Five Elements Theory covers five categories: the nature of all things in nature is accepted by others.
There exists a relationship between the five elements, promote and restrain is the two sides of contradiction, that is, the two sides of Yin and Yang. Generation and restraint are the universal laws of things and the two inseparable aspects of things. promote and restrain is relative. Without promote and restrain, there is no such thing as promote. Without promote and restrain, there is no such thing as restrain. If only promote without restrain, things will go to extremes endlessly, resulting in extreme things will turn from good to bad; if only restrain without promote, things will be depressed and go to decline because they are suppressed excessively.
