Extended data
Running script appeared at the same time as eight-part essay, and its form was very close to eight-part essay and later official script. This is equivalent to changing (chapter) cursive script from official script to other branches derived from "regular script". In addition to official script, the "regular script" in Huanling period was followed by "eight-part essay", so people think that running script is another branch of "eight-part essay".
In fact, it is the same as other calligraphy styles. It was originally founded as a general mass writer. As long as it is written in other calligraphy, it becomes a running script without official style. It can be seen everywhere in bamboo slips unearthed at the end of Han Dynasty. At the end of Han dynasty, running script was not widely used. It was not until the appearance of Wang Xizhi in Jin Dynasty that it became popular.
