At the end of the Eastern Han Dynasty, Li Shu used a slightly square pen, and the wave pen contracted or basically disappeared, and began to transform into regular script. During the Wei, Jin, Southern and Northern Dynasties (220-58 1), regular script finally became independent from official script and reached a peak in the Tang Dynasty. Regular script is one of the most commonly used characters when learning to write Chinese characters. Letters of Warring States Policy, Lao Zi A and B, Hanyang Heyang Li Yuan, Hanwu Taishou, etc.

Cursive script was also formed in the Han Dynasty. As the name implies, "grass" means "sloppy". Perhaps because of the tight time, the structure of the rules could not be taken into account, and it was first written as an emergency work. Although the structure of cursive script is loose, it is the biggest space for the writer to play freely, and it can best reflect the writer's personality characteristics, so it has always occupied an important position in the history of calligraphy.

Running script is a kind of calligraphy between regular script and cursive script. The structure and stippling of running script are close to regular script, but it absorbs the advantages of cursive script in turning and coherence. Therefore, running script is more convenient and faster than regular script, and clearer and easier to recognize than cursive script, so it is widely welcomed by people. Running script is one of the most commonly used characters when writing Chinese characters in daily life. Preface to Lanting Collection, Sacrifice to Nephew, Cold Food Post
