Official script: Qin Li, Han Li, etc. Generally speaking, it is developed from seal script, with wide and flat glyphs, long horizontal paintings and short vertical paintings, and pays attention to "swallow tail of silkworm head" and "twists and turns".
According to the unearthed bamboo slips, Lishu originated in the Warring States Period. Legend has it that Qin Shihuang, in the process of "writing the same text", ordered Li Si to create Xiao Zhuan, and later adopted the official script compiled by Cheng Miao. After Xu Shen recorded Ying Zheng's unified writing in Shuo Wen Jie Zi in Han Dynasty, the history of traditional writing was revived and excavated in Han Dynasty: "... Qin burned scriptures, washed away the old, officers and men made outstanding contributions, promoted military defense, and had numerous official positions and prison posts. At first, it was an official script, so it was fun, and the ancient prose was lost. "
Han Li reached its peak in the Eastern Han Dynasty, which had a great influence on later calligraphy. Calligraphy is known as "Han Li Tang Kai". Qin Shihuang played a great role in Chinese characters in China, which is of great significance to the unification of Chinese characters and nationalities in China today.
