Qin Shihuang unified the writing.

Since the Shang Dynasty, writing has gradually become popular. As an official language, bronze inscriptions are relatively consistent in form. However, during the Spring and Autumn Period and the Warring States Period, there were regional differences in folk characters, such as weapons, Wen Tao, silk books and bamboo slips. This situation has hindered the economic and cultural exchanges between different places, and also affected the effective implementation of policies and decrees of the central government. So, after Qin unified the Central Plains, Qin Shihuang ordered Li Si and others to sort out the unified characters.

On the basis of the big seal script commonly used by Qin people in the Warring States Period, Li Si absorbed the advantages of the stick figure and strokes in tadpole seal script commonly used in Qilu and other places, and created a new seal script with uniform and neat shape and simple strokes. Qin Zhuan? Also known as? Xiao zhuan? , as the official standard text, while abolishing other variants. In addition, an official named Cheng Miao was detained in Yunyang for committing a crime. During his 10 years in prison, he changed the font evolution at that time (later called? Change? ), make a summary. This move was appreciated by Qin Shihuang, so he was released, promoted to suggestion and ordered? Book ordering? , develop a new font, that is? Official script? . Official script broke the tradition of ancient Chinese characters, laid the foundation of regular script and improved the writing efficiency.
