The historical origin of seal
The oldest lettering in China is the stone carvings of Oracle Bone Inscriptions, Zhou and Qin in Yin. All words engraved on gold, copper, jade and other materials are generally called "Jinshi". The seal is contained in the "stone".
There is no conclusion about the origin of Xi seal in Shang Dynasty. According to relics and historical records, it appeared at least in the Spring and Autumn Period and the Warring States Period, and it was widely used in the Warring States Period. At first, it was only used as a voucher for commodity exchange. After Qin Shihuang unified China, the scope of the seal was expanded to prove the rights and interests of those in power, and it was held by those in power as a tool for ruling the people.
During the Warring States Period, Su Qin, which advocated unity, wore the seals of the six countries. The cultural relics unearthed in recent years have pushed the history of seals forward for hundreds of years. In other words, seals existed in the Zhou Dynasty.
