Running script is a kind of calligraphy, which is divided into running script and running script. It is developed and originated on the basis of regular script, and it is a font between regular script and cursive script, which is produced to make up for the slow writing speed of regular script and the illegibility of cursive script.
Line means walking, so it is not as scribbled as cursive script, nor as straight as regular script. Whether it is cursive or cursive in essence. There are more methods of mold opening than cursive writing, which is called "mold opening".
Cursive calligraphy is more than modular method, which is called "cursive calligraphy". Running script is both practical and artistic, and regular script is a literal symbol, which is practical and skillful; Comparatively speaking, cursive script is highly artistic, but its practicality is relatively insufficient.
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 cursive script from official script and deriving other branches from "regular characters".
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, like other calligraphy styles, it was originally founded by ordinary popular writers. As long as it is written with other calligraphy, it will become a running script.
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.
