According to the unearthed bamboo slips, official script originated in Qin Dynasty, and Cheng Miao was also called official script. Han Li reached its peak in the Eastern Han Dynasty, inherited the tradition of seal script, and opened the Wei, Jin, Southern and Northern Dynasties, which had a great influence on later calligraphy. The calligraphy circle is known as "Tang Kai of Han Li". Li Shu, including Qin Li and Han Li, is generally considered to be developed from seal script, with wide and flat font, long horizontal painting and short vertical painting, and paying attention to "silkworm head and goose tail" and "twists and turns".
Extended data Cheng Miao, whose name is Cen, was born in Xiazhao (now Weinan North, Shaanxi Province) in the history of Qin Dynasty. He was a small official in the Qin Dynasty. He once worked as a county magistrate and was responsible for paperwork and other errands. Because of his honest temperament, he offended Qin Shihuang and was put into Yunyang prison.
Cheng Miao collected all kinds of calligraphy styles circulated by the people, studied them with great concentration and improved them one by one. At the same time, after ten years of processing and sorting, he finally created 3,000 official script characters that are easy to write and identify. He dedicated this achievement to Qin Shihuang.
Qin Shihuang worked very hard when he was young, and he was a man who paid great attention to work efficiency. After the unification of the world, there are so many political, cultural and economic reforms to be promoted. He works day and night and forgets to eat and sleep.
Qin Shihuang was very happy when he read the words compiled by Cheng Miao. He not only pardoned Cheng Miao's sin, but also made him an official and promoted the empire. Because Cheng Miao's official position is very small, he belongs to "Li", so people call his words "Li".
At the same time, "official" also refers to "petty official", that is, a small official in charge of documents, so in ancient times, Li Shu was also called "auxiliary book". This kind of official script is characterized by flat width, simple structure, straight strokes and waves. Compared with Xiao Zhuan, it is convenient to write and easy to identify. Later, in order to distinguish it from the official script of Han dynasty, it was called Qin official script.
