Seal art is a part of China's long history and culture. Since the Warring States Period, the names of seals have evolved several times, and different dynasties have different names. Seals are the earliest names of seals. Before the Qin Dynasty, both official and private seals were called seals. But the word "Xi" in ancient times was written as "Xi". Those who use copper for printing use gold, and those who use earth use earth.

Before the Qing Dynasty, many people who studied seals did not know this word. It was not until the Qing Dynasty that Cheng made a preface to "The Seal of Wang Yin Fu" that the word "seal" was released. After Qin Shihuang unified the six countries, he formulated a series of hierarchical systems and set up the "Jeffling City" in charge of the seal system in Shaofu.

At that time, it was stipulated that only the emperor's seal could be called "seal", and its material was jade. The seals of all subjects are called "seals", and jade is not allowed as its material. However, in the existing Han seal, not only emperors, but also emperors of past dynasties called it "seal", such as "Empress Seal" and "Huaiyang Wang Yin". This is because although the Han Dynasty also inherited the system of the Qin Dynasty, the system has been slightly relaxed, so the seal used by the princes and queens can also be called "seal".

According to "Han Guan Yi", there were six seals for the emperors in the Han Dynasty, namely, Emperor Seal, Emperor Seal, Emperor Seal, Emperor Seal and Emperor Seal. They are all white jade tiger buttons. It is said that the seal was carved by Li Si and given to Yu Gong Sun Shou. Seals were first seen in the official seals of Qin Dynasty, such as "Changwu County Seal" and "Ye Yi Township Seal". Changwu is a county name located near Ye County, Shandong Province, and "Jun" is the title of feudal Lord.
