Running script is a font between regular script and cursive script, which can be said to be cursive script or cursive script. It is to make up for the shortcomings of slow writing in regular script and illegible cursive script. The brushwork is not as sloppy as cursive script, and it is not required to be as correct as regular script. 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 was produced in the late Eastern Han Dynasty.
The word "running script" is pronounced as "Shu Hang", so it is called "Shu Hang" because it is a kind of writing used by ordinary businessmen in ancient times to record the quantity of goods bought and sold. This is wrong and should be read as "running script". Some people don't understand the original intention of lines. Su Dongpo, a calligrapher in the Song Dynasty, said, "Just open the letter." They think that the "running script" is named after the walking position, which is all wrong.
