After the Qin Dynasty unified China, a series of measures were taken to consolidate the unified political structure, among which "the same language" was one of them. In order to unify the writing, Qin ordered Lisi to write, Zhao Gao to write calendars, and Hu Wujing to write and learn, which were collectively called "Three Cang". This is the seal script created by Qin. It is also said that Cheng Miao, a jailer in Qin Dynasty, spent 65,438+00 years reforming seal script and creating official script, which was affirmed and popularized by Qin Shihuang. The official script created by Cheng Miao is unknown, but we can imagine the general situation of Li Cheng's official script with some seal characters (that is, "ancient characters") from Sleeping Tiger Bamboo Slips to Emperor Wu of the Han Dynasty. Or it is because this kind of official script is simpler and easier to write than the big seal script and the small seal script, and later replaced the seal script and became the main text before the end of the Han Dynasty and the Three Kingdoms. The works handed down at that time were mainly stone carvings of the Qin Dynasty. Qin Shihuang made many tours, and everywhere he went, he often set up tablets and carved stones to publicize his unified achievements. There are seven kinds of recorded stone carvings: Langyatai stone carving, Taishan stone carving, Yishan stone carving, Huiji stone carving, Jieshi stone carving, Zhelanggai stone carving and Dongguan stone carving. However, according to the identification of ancient philologists, only the "Langyatai carved stone" is the original stone, and the others were carved or copied by later generations.
