Huangdi Neijing has been bought for many years, and I can't understand it. Yesterday, I came across a conversation between Liang Dong and Xu Wenbing, which I found very interesting.

The book begins with the fourth chapter "Synopsis of the Golden Chamber". In this chapter, they talked about four kinds of winds-east wind, west wind, south wind and north wind. Different winds hurt different organs.

Therefore, we should pay attention to caring for different organs in different seasons.
