Cursive script can be divided into broad sense and narrow sense. Broadly speaking, regardless of the times, all scribbled words can be regarded as cursive. In a narrow sense, that is, as a specific font. Formed in the Han Dynasty, it evolved on the basis of official script for the convenience of writing. It is characterized by simple structure and continuous strokes.
The cursive script is divided into Cao Zhang and today's grass, and today's grass is divided into big grass (also called crazy grass) and small grass, which feels beautiful in madness.
