1, official script
Official script is basically evolved from seal script, mainly changing the round strokes of seal script into square folds. Because it is difficult to draw round strokes on wooden slips with pigments, the official script is written faster.
2. Regular script
Regular script evolved from Han Li, which can be divided into Weibei and Tang Kai. Weibei refers to the calligraphy style in Wei, Jin, Southern and Northern Dynasties, which can be said to be a style of transition from official script to regular script.
Regular script in a narrow sense refers to Tang Kai, which gradually matured after the Tang Dynasty. Its representatives are Ou Yangxun, Yu Shinan, Chu Suiliang and Xue Qi in the early Tang Dynasty, Yan Zhenqing in the middle Tang Dynasty and Liu Gongquan in the late Tang Dynasty. We often say that the four masters of regular script "Yan Liu Ou Zhao", the first three are all from the Tang Dynasty. By the end of the Tang Dynasty, regular script reached its peak and its style was too regular.
