3. During the Zhou Dynasty, the inscriptions engraved on bells and tripods, also known as bells and tripods, were widely popular. After the unification of Qin Shihuang, they were collectively called Xiaozhuan, also known as Qin Zhuan. The so-called seal script is actually the official script (掾yuàn, which is an official position, probably following the system of the Qin Dynasty). It is a standardized common font for official documents.
4. The originator of Xiaozhuan, Li Si, whose courtesy name was Tonggu, was a native of Shangcai (now Shangcai County, Henan) during the Warring States Period. Later, he became the Prime Minister of Qin and organized and formulated Xiaozhuan, the standard calligraphy style of Qin Dynasty.
