Stone inscriptions originated in the Zhou Dynasty and flourished in the Qin Dynasty. The Qin State carved stone characters during the Eastern Zhou Dynasty. Each of the 10 granite drum-shaped stones is engraved with a four-character poem, which sings about the hunting situation of the king of Qin, so it is also called hunting tablets. The earliest stone carving in the legend is the "Si Stele" from the Xia Dynasty. The style of the carved poems is similar to that of the "Book of Songs". The font is close to the text contained in "Shuowen Jiezi", and his calligraphy has always been highly praised. The main works include: "Shiguwen", "Yishan Stone Carvings", "Taishan Stone Carvings", "Langya Stone Carvings", "Kuiji Stone Carvings", etc.
