Shi Guwen is the earliest stone carving in China. It is a seal script carved on ten drum-shaped stones, hence the name. The diameter of the drum is about two feet, and the words are engraved in the middle of the stone drum. The content of the text is a four-character rhyme, which describes Qin's hunting, so it is also called "hunting". Until the early Tang Dynasty, the stone drum was abandoned in the field of Chencang (now Fengxiang, Shaanxi), so it was called "Chencang Stone Drum", and because it was located in the grandson of Qishan, it was called "Qiyang Stone Drum". Shi Guwen's calligraphy style is between the bronze inscriptions of the Zhou Dynasty and Qin Xiaozhuan, or "Dazhuan", and some people call "Shigu" written by historians, so it is called "Shu Shu".
