The development of Chinese characters has experienced the Western Zhou Dynasty (Dazhuan), Qin Dynasty (Xiaozhuan) and Han Dynasty (Lishu).

Dazhuan was a widely used font in the Western Zhou Dynasty? . According to the different writing media, there are differences between bronze inscriptions (or "Zhong Dingwen") and bronze inscriptions.

After Qin Shihuang unified China (22 1 year ago), Xiao Zhuan implemented the policy of "writing is similar, cars are on the same track", and Prime Minister Li Si was responsible for the unified measurement. On the basis of the original script of the Qin Dynasty's Da Zhuan, Xiao Zhuan simplified it, canceled the other six scripts, and created a unified Chinese writing form.

Developed from seal script, the fonts are mostly wide and flat, with long horizontal paintings and short vertical paintings, and pay attention to "swallow tail of silkworm head" and "twists and turns". Lishu originated in the Warring States Period and reached its peak in the Eastern Han Dynasty.
