Regular script, also called modern script, original script, regular script, regular script or regular script, is a common handwritten font style in China's calligraphy. According to legend, it was used by Wang Ci-zhong during the reign of Emperor Zhang of the Han Dynasty. It is a variant of Lishu, and its glyph is relatively straight and square.

Li Shu's stroke's tail-picking method and silkworm's head-swallowtail method are not flat writing, and their structure does not conform to the modern principle of "six calligraphy". Regular script is still the reference standard of China's calligraphy. Regular script was also called official script in ancient times. The origin of the word "Zhengshu" can be found in Xuanhe Pu Shu in the Song Dynasty. "True Book" and "True Book" are homophones.

The word "positive" is from "stop" to "one". Therefore, the word "positive" has a foothold, is impartial, and stops at the best level. English and other western words such as regular script are also translated from the word "official script".

There were few early official scripts, with a slightly wider structure, long horizontal painting and short straight painting. Wei Jinzhong, handed down from generation to generation, such as Zhong You's Declaration Form, Ji Zhi Table, Wang Xizhi's Theory of Music and Huang Tingjing, can all be regarded as representative works.

The four most famous writers of regular script calligraphy are:

Tang, Ou Yangxun (European style).

Don, Yan Zhenqing (Yan Ti)? Yan Zhenqing was a great calligrapher in Tang Dynasty and a native of Shandong. Representative works of regular script include "Many Babies" and "Ma Gu Xian Tan Ji".

Tang, Liu Gongquan (Liu Ti)? Liu Gongquan was also a great calligrapher in the Tang Dynasty, a native of Shaanxi, born after Yan Zhenqing. His regular script is rigorous and vigorous. His masterpiece is the mysterious tower monument.
