1. Xiao Zhuan, also known as Qin Zhuan, is a well-known text compiled by Prime Minister Li Si after the reunification of Qin. Before the reunification of the Qin Dynasty, due to the long-term regional separatist regime, "different sounds and different characters", the writing form was very inconsistent, and the phenomenon of more than one character was very serious. For example, there are more than twenty ways to write "sheep", which brings great inconvenience to the development of economic and cultural exchanges. Therefore, while unifying the system of money, rail and weights and measures, we also strive to implement the policy of "book peers". The preface to Shuo Wen Jie Zi records that "Prime Minister Reese played with it and didn't cooperate with it. The secretary wrote "Heaven and Heaven", Che Fu ordered Zhao Gao to write "Love Calendar", and Tai Shi ordered Hu Wu to write "Bo Xue", all of which took history as a great seal, or it was quite preserved, so-called small seal. " It can be seen that the system of Xiao Zhuan evolved from Da Zhuan. On the basis of prose writing, Li Si simplified the complicated and abolished the variant characters, and created Qin Zhuan with unified national characters. This kind of book is relatively simple, with horizontal lines and vertical characters. This is a great progress of Chinese characters and an important milestone in the development history of Chinese characters. It opened up a broad road for the changes of later books such as Kai, Li, Xing and Cao. Some of them are cast on iron, and some are carved on stone tablets and stone tablets. There are large and small characters, natural composition, dignified words and neat branches, which are the essence and representative of Xiao Zhuan. His masterpiece is the remains of Qinshan stone carving, with only the word 10 left. In addition, the rubbings of Mount Tai and Langyatai are handed down from generation to generation. It is said that all the carved stones on it were written by Li Si.
2. Mr. Xu, a famous scholar and calligrapher, believes that it is impossible to create a character overnight in the extremely short Qin Dynasty, and it takes a long time to form a character. Qin Shihuang only processed, sorted out and popularized the seal script that had been formed during the Warring States Period.
