In 22 1 year BC, after Qin Shihuang destroyed the six countries and unified China, he was awarded the prize. Qin Shihuang carved it into a national seal, and ordered Prime Minister Lisi to write eight characters of insects and birds on the stone wall, which was carved by jade worker Sun Shou. After Qin Ershi's death, Zi Ying presented the imperial seal handed down from ancient times to Liu Bang, the Emperor Gaozu of Han Dynasty, and awarded him the "Imperial Seal of Han Dynasty". After Wang Mang usurped power, he forced Suo Yuxi to the Empress Dowager Xiao Yuan. The empress dowager was furious and threw the national seal on the ground and broke a corner. Wang Mang set it with gold. Although the craft is exquisite, the bag has left traces of missing corners after all.
At the end of the Eastern Han Dynasty, when various governors crusaded against Dong Zhuo, Sun Jian, who took the lead in attacking Luoyang City, got a red box on the body of a maid-in-waiting in the well, and what was in the box was the official seal. (See Wu Zhi) Later, Sun Ce, the son of Sun Jian, presented an imperial seal to Yuan Shu and borrowed military forces. Sun Ce exchanged this seal for 3,000 soldiers in Yuan Shu, thus establishing Sun Wu's dominance. After Yuan Shu failed to proclaim himself emperor, the decree was returned to Cao Cao.
