Cursive script is a font of Chinese characters, which is characterized by simple structure and continuous strokes. Formed in the Han Dynasty, it evolved on the basis of official script for the convenience of writing. There are Cao Zhang, modern grass and weeds, and it feels beautiful in madness.
There are rules to follow in the changes of strokes, such as the urgent chapter of the Three Kingdoms Wu in Songjiang Edition. Today's grass is eclectic and fluent, and its representative works include Wang Xizhi's "The First Moon" and Jin Dynasty's "Getting Time". Mad grass appeared in the Tang Dynasty, represented by Zhang Xu and Huai Su, and its brushwork was wild and uninhibited, which became an artistic creation completely divorced from practicality. From then on, cursive script was only the works of calligraphers imitating Cao Zhang, Cao Jin and Kuangcao. The representative works of Weeds, such as Abdominal Pain by Zhang Xu in the Tang Dynasty and Autobiographical Postscript by Huai Su, are all existing treasures.
