The original classification method of Cao Zhang and Cao Jin in cursive script is still the classification method at the end of Han Dynasty. Grass today is a concept of time, which has been used for thousands of years. Later, I gradually stopped using the name of this grass. There are roughly three classification names of new cursive scripts: one is Cao Zhang, the other is Cao Cao, which refers to cursive scripts with independent characters, and the third is Dacao or Kuangcao, which refers to cursive scripts with hyphens. The other is to list weeds except weeds. Divided into chapter grass, cursive script and weeds.
