The early cursive script broke the strict rules of official script and was a hasty writing. It's called Cao Zhang. Cao Zhang was the most popular in the Han and Wei Dynasties, but it was revived in the Yuan Dynasty and transformed into the Ming Dynasty. At the end of the Han Dynasty, Cao Zhang was further "grassed" and the strokes of Lishu were removed. The upper and lower characters and strokes are connected, and the radicals are simplified and borrowed, which is called "modern grass".
Today, the aesthetic value of cursive script far exceeds its practical value. One of the main features of cursive script is that the strokes are connected by hooks, with up and down hooks and left and right hooks. Cao Zhang's brushwork is "one" and modern cursive brushwork is "s". This is the fundamental difference between the two. Indulge with a pen, draw messy, also called big grass or crazy grass.
Extended data:
The word official script is written like this:
Li Shu, including Qin Li and Han Li. It is generally believed that it is developed from seal script, with wide and flat font, long horizontal painting and short vertical painting, and pays attention to "silkworm head and goose tail". Han Li reached its peak in the Eastern Han Dynasty, which had a great influence on later calligraphy. Calligraphy is known as "Han Li Tang Kai".
Official script is basically evolved from seal script, mainly changing the round strokes of seal script into square folds. Because it is difficult to draw round strokes on wooden slips with pigments, the official script is written faster. The formation of the independent character and aesthetic characteristics of official script was not the high level and maturity in the Eastern Han Dynasty, but existed in the process of official script reform for more than 400 years.
In addition to development, official script also had an impact on Wei Bei regular script. Take the tablet of Zhang Menglong as an example, there is some official script spirit in the words. Don was also affected.
