Regular script, also called official script or original script, is a common font in China's calligraphy. Its glyph is square, unlike the flat one written in official script. Regular script is still the reference standard of modern calligraphy in China, and another kind of calligraphy, pen-and-ink, has also developed.
Cursive script is a loose title. In a broad sense, it refers to a scrawler, and in a narrow sense, it refers to a font with continuous strokes and convenient writing. Generally speaking, the popular calligraphy in the early Han Dynasty was cursive script (that is, scribbled official script), which gradually developed into "Cao Zhang". By the end of the Han Dynasty, it was said that Zhang Zhi's "Cao Zhang" contained traces that the strokes of official script were not connected with the characters, and became a "modern cursive script" with simple strokes, many symbolic parts and continuous and convenient strokes, which was later called cursive script. Wang Xizhi of the Eastern Jin Dynasty perfected it, and Tang Huaisu carried it forward as crazy grass, which was the highest realm of cursive writing. Cursive script is a wonderful flower in calligraphy. The control in the process of rapid writing and the release of the writer's instinct show the essence of calligraphy.
Running script is developed and originated on the basis of regular script, which produces a font between regular script and cursive script to make up for the slow writing speed of regular script and the fuzziness of cursive script. "Go" means "go", so it is not as scribbled as cursive script, nor as straight as regular script. Whether it is cursive or cursive in essence. Those with more patterns than grass patterns are called "running patterns", and those with more grass patterns are called "running grass".
Lishu, also called Han Li, is a solemn font commonly used in Chinese characters. Its writing effect is slightly wide and flat, the horizontal painting is long and straight, and it is rectangular, paying attention to "silkworm head and goose tail" and "twists and turns". Lishu originated in the Qin Dynasty, formed by Cheng Miao, and reached its peak in the Eastern Han Dynasty. Calligraphy is known as "Han Li Tang Kai".
