Lishu is mainly divided into: Han Li and Qin Lishu.
Li Qin
In the process of "writing in the same language", Qin Shihuang ordered Li Si to create Xiao Zhuan, and also adopted the official script compiled by Cheng Miao. Xu Shen of the Han Dynasty recorded this history in Shuo Wen Jie Zi: "... Qin burned books, purged the old people, officers and men made outstanding contributions, were promoted to military service and defended, and there were countless officials and prisons. At first, it was an official script, for the convenience of agreement. " As an official script, Xiao Zhuan's writing speed is slow, which turns official script into a square fold and improves writing efficiency. Guo Moruo used "the greater achievement of Qin Shihuang's reform of writing was the adoption of official script" to evaluate its importance (the development of the debate on ancient Chinese characters in the slavery era).
Hanshu (a popular writing form in Han Dynasty)
At the beginning of the Western Han Dynasty, Qin Li's style was still used, but it began to change greatly in the Xin Mang period, resulting in the writing method of stippling. By the Eastern Han Dynasty, Lishu had produced many styles and left a large number of stone carvings. Zhang Qianbei and Cao Quanbei are the representative works of this period.
official script
Lishu, also called Han Li, is a solemn font commonly used in Chinese characters. Its writing effect is slightly wide and flat, the horizontal painting is long and straight, and it is rectangular, paying attention to "silkworm head and goose tail" and "twists and turns". Lishu originated in the Qin Dynasty and was compiled by Cheng Miao. It reached its peak in the Eastern Han Dynasty, which had a great influence on later calligraphy. Calligraphy is called "Tang Kai of Han Li".
