Yin and yang （阴阳）

Yin and Yang is a simple and broad ancient Chinese philosophy.

Yin-yang philosophy has three characteristics: unity, opposition and mutual transformation. In thinking, it is an inseparable metaphysical node of calculation (arithmetic) and divination (logic). In nature, the gene of organism and the binary system of artificial intelligence fully demonstrate the vitality of Yin and Yang.

Yin and Yang are the descriptions of the fundamental factors behind the laws of nature in ancient Chinese civilization, which are the motive force for the nurture, development, maturity, decline and death of all kinds of things, and the core elements for laying the logical thinking foundation of Chinese civilization.

There are four pairs of relationship between Yin and Yang: Yin and Yang mutually, Yin and Yang cultivation, Yin and Yang opposition, Yin and Yang roots.

Traditionally, Yin and Yang represent the most basic opposition of all things. It is the objective law of nature, the origin of the movement and change of all things, and the basic law of human understanding of things. The concept of Yin and Yang originated from the view of nature of the ancient Chinese people. The ancients observed various natural phenomena, such as heaven and earth, sun and moon, day and night, cold and heat, men and women, upper and lower, which were opposite and interrelated in nature. They summed up the concept of Yin and Yang in a philosophical way.

which means they are closely related to each other
The position of Yin and Yang is constantly changing, recurring. What we can see is Yin, Yin, Yin and Yang (which is the aggregation of positive matter to form Yang above), and vice versa (similar to black holes). Everything must conform to the law and structure of Yin and Yang, just as people are born (aggregation), and then die (dissipation). This is the law of Yin and Yang, and the imbalance of Yin and Yang or the wrong position of Yin and Yang in the human body will make people sick.
