In order to give full play to the role of sketching, scribbling is omitted, and it is naturally impossible to write neatly. As the name implies, it is cursive. I prefer the records in Historical Records. The cursive script was originally produced for shorthand. For example, officials in charge of records, such as bookkeepers and assistant ministers, can't return a neat record when the boss speaks. Writing is too slow and inefficient. What a sin it would be if there were omissions.
Today, the artistic value of cursive script far exceeds its practical value. So where is the beauty of cursive script? Later, people explained that "cursive script is in a hurry" and said that cursive script had no time to organize ideas. This is entirely from the understanding of cursive script in later generations. By the Song Dynasty, regular script had become the only way for people to learn calligraphy.
In addition, people can only learn cursive script from rubbings such as Seventeen Posts. Except for a few people, all cursive scripts in the world are just empty shells, and the rhythm is completely wrong. Even if we spend less time with pens now, we can't write as good articles as the ancients, but there must be a boundary and a bottom line between beauty and ugliness.
