Yin and yang and five elements, the sky is qi and the earth is quality. Everything is born in spring, everything is born in summer, everything is born in autumn, everything is born in winter, and everything is collected in winter. This is the law of natural climate operation, just like wind, rain, thunder and electricity, which cannot be changed by scientists and is not the object of scientists' research. Humans can only make good use of these natural climate phenomena to survive.
Soil is fine, and soil is composed of these five substances: gold is gold, wood is wood, water is water, fire is fire, and soil is soil. This is naturally formed at the beginning of the creation of heaven and earth, so why is it composed of these five substances? This is not the research object of scientists. Humans can only use these five substances, but they can't create new ones. Just like men and women and animals have males and females, this is an unchangeable law.
As for the five elements, this is also the natural nature at the beginning of material production. People can only survive by using the attributes of the five elements. Scientists can only study the properties of a certain substance independently, so as to better serve human survival. For example, scientists can make airplanes, ships, cars, trains and so on by studying the properties of gold. But why can fire kill gold, gold can kill wood, soil can produce gold and gold can produce water? This is not the research object of scientists, because it is a law that can only be applied without research.
Traditional Chinese medicine is a science, and its theoretical source is yin and yang and five elements. It is a system established by using the law of Yin-Yang and Five Elements. Because people pay attention to the integrity of the five internal organs, man and nature are one, so we should take both yin and yang and five elements into account. Scientists in other fields only need to study one of the five elements.
In a word, Yin-Yang and Five Elements are not the research objects of scientists. In the face of Yin-Yang and Five Elements, scientists can only apply and utilize their properties.
