I think he, to some extent, has transformed into some concepts of western medicine, that is, some hormones of body endocrine, which can greatly affect our physical state and mood. Yin Qi is a kind of hormone, which can make our whole person more calm and calm. The transformation of Yang Qi into western medicine is a kind of hormone, which can make our body more energetic and powerful. Of course, this is my personal understanding, and it may not be true.

Yin and yang are often mentioned in Chinese medicine. When the balance of qi in our body is broken, our body will have problems, or we will have a cold and fever, or the internal organs of a certain body organ will have problems and various diseases, all because the balance is broken.

So from the perspective of Chinese medicine, we pay great attention to the balance of the body. We should use some drugs or living habits to ensure the balance of Yin and Yang in our bodies and keep our bodies in a healthy state. Although these ideas are now moved to western medicine, no one may agree with him, but I think he is very correct from the perspective of health preservation. We should conform to the four points, and then adjust the balance of various hormones and states in the body to keep the body in a balanced state.

More is to make our bodies more balanced. The human body is a very complicated system. It's like a balance. It will add various weights. If one side is out of balance, it will lead to problems in our bodies. For example, if the yin is too heavy, people may be introverted, and then they will be weak. If the yang is too heavy, it may lead to frequent insomnia.
