Extended information:
There is no authoritative conclusion on the origin of running script. Historically, it has been said that creation is attributed to a certain person, but in fact it may not be something that an individual can do. As long as we examine the discovered objects and documents from the perspective of dialectical materialism, it is not difficult to draw more credible scientific conclusions. The first running script appeared around the late Western Han Dynasty and the early Eastern Han Dynasty. At that time, not only running script appeared, but also there were calligraphers.
The earliest running script should have appeared in practical use and was a writing method that started among the people. For example, in the "Juyan Han Bamboo Bamboo Slips" at the end of the Western Han Dynasty and the beginning of the Eastern Han Dynasty, the writing method is neither one stroke nor one stroke. The written official script is not the style of cursive script. The structure, simplicity of writing and the connection of stipples already have the characteristics of running script.
However, it may not be appropriate to say that running script evolved from regular script. From the perspective of the development of running script, regular script and running script are different writing styles that evolved from the official script at the same time. They influence each other in the early stages of the development process. However, running script matures faster than regular script, and cursive script changes to modern cursive script faster than regular script.
From Zhangcao to Jincao, it matured around the end of the Han Dynasty, the Three Kingdoms, and the Western Jin Dynasty. Only after the Eastern Jin Dynasty did the highly mature and artistic cursive script come into being.
