Cursive script (East Asia)

The grass script or concept font (Chinese草书, Pinyin Cǎoshū, Japanese草书sōsho ) is one of the five main categories of Chinese calligraphy. The name comes from the rapid manner in which it is executed. It is believed that this style of writing by Liu Desheng developed in the Han Dynasty and was developed by Wang Xizhi and Wang Xianzhi, two calligraphy masters of the Jin Dynasty.

There are many subcategories of grass or concept writing, for example, the "crazy concept writing" (狂草, kuángcǎo ), which is no longer legible and no longer even trying to be legible. Instead, it involves an art form. The common features of all concept font styles are quickly written and flowing lines, often a highly simplified structure of the characters running into each other dashes and low readability. Among the five styles of Chinese calligraphy is the writing concept of abstract art the next.
