Overview: You write your own name on the paper, and then ask the seal engraver to carve a seal according to the name you signed. In the future, the seal will be directly stamped where your signature is required. You stamped this seal. Documents and books are then printed, which is called signed information, and books are called signed copies. If fans buy your book, this kind of book is called signed edition (similar to a signature).

The origin of the seal:

The oldest Chinese carved characters include the oracle bone inscriptions of the Yin Dynasty, the bell and tripod inscriptions of the Zhou Dynasty, and the carved stones of the Qin Dynasty. They are all carved on gold, copper, jade and other materials. The characters are commonly known as "Jinshi". The seal is included in the "gold and stone".

The origin of the seal may be said to be the Shang Dynasty or the Yin Dynasty, but there is still no conclusion yet. According to relics and historical records, it appeared at least during the Spring and Autumn Period and the Warring States Period, and was widely used during the Warring States Period. At first it was only used as a certificate when exchanging goods in business. After Qin Shihuang unified China, the scope of seals expanded to legal objects proving the rights and interests of those in power. They were held by those in power as a tool to rule the people.
