After the Qin Dynasty unified China, it took a series of measures to consolidate its rule, including the famous "Wentong Calligraphy", which unified the different writing styles used by various countries in the Warring States period into the so-called Xiao Zhuan, which was said to have been invented by Li Si, the prime minister of Qin Dynasty.
According to Records of the Historical Records of Qin Shihuang, after the reunification of the whole country in 26 years (22 BC1year), the king of Qin implemented the policy of "measuring stones with one foot, one car on the same track, and writing the same word". The policy of "writing with the same character" is not only of great significance to the newly established Qin Dynasty, but also has far-reaching influence on later generations.
The word "calligraphy with the same character" can be found in Records of the First Qin Emperor;
Divide the world into 36 counties, with guards, guards and supervisors. Renamed "Thousand Hands", Daan people. Soldiers from all over the world gathered in Xianyang and sold them as Zhong Yi and Ren Jin, each weighing thousands of stones, and put them in the palace. A scale, cars are on the same track, and so are books.
Extended data:
Before Qin Shihuang unified the Central Plains, the characters of different countries were also very different. Even the same word can be written in several ways.
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. Since then, more convenient calligraphy has been adopted and unified characters have been stipulated. In this way, cultural exchanges between different places are much more convenient. ?
