Dazhuan is a widely used font in the Western Zhou Dynasty, and it is said that it was created by Boyi in the Xia Dynasty. After Qin Shihuang unified China (22 1 year ago), Xiao Zhuan implemented the policy of "the words are the same, the cars are the same", and unified measurement is responsible. On the basis of the original script of the Qin Dynasty's Da Zhuan, it was simplified, and the variant characters of the other six countries were cancelled, creating a unified writing form of Chinese characters. In Wei Ti, people will naturally think of the strict and formal official script of the Northern Wei Dynasty, which was mainly composed of stone carvings during the Wei, Jin, Southern and Northern Dynasties. When it comes to running script, people will habitually associate it with the elegant and free-and-easy styles of the two kings in the Eastern Jin Dynasty or the Su, Huang, Mi and Cai schools in the Northern Song Dynasty, which are now combined into a running script and shine brilliantly in the book world. This calligraphy style was later called "Wei Ti's running script". 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". The inkstone body was created by Yan Zhenqing, a calligrapher in the Tang Dynasty. Together with Liu Gongquan, it is called "Yan Liu" and "inkstone Liu Jingu". "Yan Ti" is aimed at Yan Zhenqing's regular script. Its regular script structure is square and dense, the strokes are horizontal and light, the brushwork is vigorous and round, and the momentum is solemn and vigorous.
