According to the written materials of Qin dynasty discovered by archaeology, the late Warring States period was the period when official script was formed. In daily use, Qin people constantly destroyed and reformed regular script, which led to vulgar style, which was the basis of official script. "In these common characters, there are a lot of writing styles that are the same or similar to those of later official scripts. In the folk characters of Qin State, it is quite popular to change the circle-to-pen diameter of the regular seal script with the method of square folding.
"This is the beginning of this text. Because the official script is not easy to write, around the middle of the Eastern Han Dynasty, the official script used in daily life evolved into a simple vulgar style, which was obviously different from Bafen. This kind of vulgar official script largely abandoned the brushwork of picking up a pen when collecting.
At the same time, it also accepted some influences of cursive script, such as more use of sharp pens, which showed an excessive appearance from eight points to regular script. In order to distinguish it from the official official official script, let's call this font the new official script. At the end of the Eastern Han Dynasty, a new font, running script, also appeared. It is said that it was created by Liu Desheng during the reign of Emperor Huan and Emperor Ling. It is a font between regular script and modern grass.
