Which dynasty did the font "Weibei" come from?

Weibei, also known as the North Monument, is a new calligraphy style that appeared in the Southern and Northern Dynasties. Mainly seen in stone carvings at that time, it is the general name of stone carving calligraphy in the Northern Wei, Eastern Wei, Western Wei, Northern Qi and Northern Zhou Dynasties.

In the Han dynasty, the popular font was official script. After the Eastern Jin Dynasty, regular script became popular in the south. At that time, people regarded the southern culture as the authentic culture of the Han nationality. The popular regular script in the south is called "regular script", which is highly praised by scholars. However, in the Northern Dynasties, Han Li's calligraphy style was directly adopted. Because it is necessary to chisel with a knife in the actual carving operation, a unique calligraphy form-"Shu Wei" is formed, which is different from Han Li and modern calligraphy. Shu Wei's font has the meaning of official script, which is simple and vigorous, fluent and powerful, and tends to be cut with knives and axes. Many in Weibei belong to this font.
