Seeking Yang from Yin is a treatment based on the relationship between Yin and Yang.

The theoretical basis of seeking Yang from Yin is the growth and decline of Yin and Yang, because the relationship between Yin and Yang is mutual root and mutual use.

The theoretical basis of seeking Yang from Yin is the growth and decline of Yin and Yang. Because yin and yang are interrelated, the deficiency of yin and yang caused by the loss of yang and yin should be based on tonifying yang and seeking yang in yin. Therefore, the theoretical basis of seeking Yang from Yin is the growth and decline of Yin and Yang.

Yin and Yang is a simple and broad philosophy in ancient China. The philosophy of Yin and Yang has three characteristics: unity, opposition and mutual transformation. In thinking, it is an inseparable metaphysical node between calculation (arithmetic) and divination (logic). Biological genes in nature and duality in artificial intelligence fully show the vitality of Yin and Yang.

The relationship between yin and yang is mutually rooted.

Lonely yin is not born, and lonely yang is not long. In the process of life activities, if the normal relationship between Yin and Yang is destroyed, it will lead to diseases and even life-threatening. Under pathological conditions,

Deficiency of yin and yang in human body will cause losses to the other party, loss of yang will consume yin, and loss of yin will consume yang. That is to say, when yang deficiency reaches a certain level, because "yin can not be transformed from yang", it can further damage the body's vaginal fluid, leading to yin deficiency, which is called "Yang losing yin deficiency".

On the other hand, yin deficiency reaches a certain level, because "without yin, yang is insufficient", which can also damage the yang in the body and lead to yang deficiency, so it is called "yin deficiency and yang deficiency"

If the relationship between Yin and Yang, material and function is seriously destroyed, so that one side tends to disappear, and the other side loses the premise of existence, showing a solitary Yang or a solitary Yin state.
