About official script

Official script is basically evolved from seal script, mainly changing the round strokes of seal script into square folds, which makes writing faster, and it is difficult to draw round strokes when writing with pigments on wooden slips.

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 is the adoption of official script" to evaluate its importance.
