Xiao Zhuan, also known as Qin Zhuan, is a well-known text compiled by Li Si, the prime minister after the unification of Qin Dynasty. 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". Shuo Wen Jie Zi? Syria "remember" prime minister Reese is playing, but not with Qin Wenhe. Our company wrote Heaven and Heaven, Che Fu ordered Zhao Gao to write Love Calendar, and a surname ordered Hu Wu to write Bo Xue, all of which took history as a great seal, or existed quite a bit, so-called small seal. "It can be seen that the system of Xiao Zhuan is 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. Judging from the physical data we have seen so far, Qin Zhuan is generally carved on ironware, weights and measures, seals, coins and imperial edicts. There are big and small, natural laws, 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, Mount Tai and Langya Taiwan have been handed down from generation to generation. It is said that all the carved stones on it were written by Li Si.
