Please come in for calligraphy. What do you mean by "big grass"

Specifically, big grass does not mean wild grass. In terms of cursive script, there are roughly six kinds of sayings: wild grass, big grass, zhangcao, small grass, walking grass and now grass. There is a difference between wild grass and big grass. This difference is based on the degree of stroke connection and composition change of cursive works. It is not difficult to find this obvious difference from Zhang Xu's Four Ancient Poems, Huai Su's Autobiographical Notes and Sun's Book Score. The first two are fluent, obviously linked with strokes, and surprisingly organized, while the latter is obviously not as good as the former in these aspects. This is the difference.
