Is Guichou Day a Sheep Blade Day?

Not a sheep's blade. Sheep are "yang", which means that the sky is dry and yang, such as A, G, C, N and E, and the blade is the most prosperous branch corresponding to the yang trunk, which is Mao, You, Wu, Zi and Wu respectively. That is, Mao is the blade of Yang Jia, especially the blade of Yang Geng, and so on. No matter whether it is dry or not, because it is soft in the shade, it can only be talked about if it is dry in the sun. The reason why the word "Yang Blade" is put forward is also to illustrate its strength in the combination of stem and branch in life science. It is full of yang, full of vitality and sharp as a knife, so it is called Yang blade (sheep blade).
