Big grass comes from four books and five classics.

There is no connection between the two. "Da Cao" is a cursive script and font in Chinese calligraphy, which has the characteristics of continuous momentum and strokes, while "Four Books and Five Classics" is the general name of ancient Confucian classics in China, including university and the doctrine of the mean, so "Da Cao" and "Four Books and Five Classics" are two different concepts, and there is no direct connection between them.
