Regular script has exemplary meaning, which was first put forward by Zhang Huai in Shu Duan. People in the Six Dynasties still used it habitually, such as Yang Xin's Cai, and On the Biography of Wei Shou, saying, "Shou is a general, and Jingzhao people are good at regular script."
That is the abbreviation of "eight-point file method". It was not until the Northern Song Dynasty that the name of the official book was replaced, and its content was obviously different from the ancient name, such as the name is different from the original name and the name is different from the original name.
Song Xuanhe's Book Score: "In the early Han Dynasty, Wang Cizhong began to use official script as regular script." The regular script here actually refers to the eight-part essay created by Wang Cizhong, not the so-called regular script today. It is said: "On the tomb of Confucius, a regular script tree planted by Zi Gongzhi has straight and unyielding branches." The strokes of regular script are concise and refreshing, and must be like the branches of regular script trees.
