Qin, Han, Wei, Western Jin, former Zhao, Eastern Jin, Song, Southern Qi, Liang, Chen, Sui, Tang, Hou Liang and the later Tang all used the imperial seal handed down by Qin Shihuang, engraved with the words "I am ordered by heaven to live forever", which was made of choi. Among them, when Wang Mang usurped the Han Dynasty, he asked Zheng Jun, the queen mother at that time, for the imperial seal.
For this reason, a corner of the official seal was broken. Although the missing corner will be filled with gold in the future, the broken traces can still be seen. Li Congke, the late Tang emperor, set himself on fire, and the national seal disappeared.
In the Song Dynasty, some farmers dug up the "national seal" in the fields. Song Ting thought it was made by Qin Shihuang, but some people thought it was forged. Later, the State of Jin took this imperial seal and spread it to the Yuan Dynasty. Yuan was taken to the north when he died, and the Ming army sent troops many times and couldn't get it back. Since then, the Ming and Qing dynasties have produced a large number of jade seals to reduce the importance of the spread of jade seals.
When the Taiping Heavenly Kingdom revolted, the heavenly king also made a new decree. Tianwang's jade seal is made of sapphire, square, with a side length of 20.4 cm, a height of 2.7 cm and a buckle height of 7.4 cm. The back of the button is engraved with moire pattern, and the side of the button is engraved with double phoenix sunrise pattern. Around the seal, there are double phoenix and sunrise patterns engraved on it, dragon patterns engraved on the left and right, and water patterns engraved on the bottom. The seal was carved in official script of Song Dynasty, with 44 characters.
