The origin of cursive script:
Cursive script is a font of Chinese characters. It appeared earlier. From the early Han Dynasty, when writing official script, it was sometimes written "hastily". Because Emperor Zhang of Han Dynasty likes cursive script, it is called "",which is a kind of cursive script of official script. Cao Zhang's words are independent and close to cursive, but the difficult words are not simplified much, and the writing style remains unchanged.
Later, regular script appeared, which evolved into "modern cursive script", that is, regular script cursive script, which was written quickly, and the upper and lower characters were often written together, and the last stroke echoed the beginning. Every word is generally simplified, but it is sometimes difficult for unfamiliar people to recognize it. Generally speaking, the cursive scripts of Wang Xizhi and Wang Xianzhi are also called modern cursive scripts.
In the Tang Dynasty, cursive script has become a kind of calligraphy art, and it has evolved into "wild cursive script", and its function as a tool for transmitting information has weakened, becoming a work of art. It doesn't matter whether people can recognize what they are writing as long as they pay attention to the black and white arrangement of bookshelves and papers.
In Weeds, there is a symbol of word association, that is, two words (common phrases) are written into one symbol. At that time, writing was mostly vertical, and even the design of Chinese characters was similar. There are cursive couplets in Tu Tou Ji and Nirvana Ji.
Modern people generally learn cursive script from today's cursive script. The recognized cursive writing method is more than the standard cursive written by Mr. You Ren (with copybook of the same name). However, Li Zhimin, a great calligrapher, pioneer and professor of Peking University, disapproved of Yu Xiansheng's standard cursive script. In his view, the art of calligraphy has its own law of development, which should be colorful, and there is no need to force unity. Reading ancient and modern works is also "the most taboo to favor one good and exclude all beauty."
