The 图章 is a cornerstone of Chinese administrative and artistic tradition, with a history spanning over 3,000 years. Originally, seals were symbols of imperial and governmental authority, with the emperor's seal (玉玺, yùxǐ) representing the ultimate power. This tradition has trickled down through society, embedding the concept of the seal as a mark of authenticity and power. In contrast to a Western signature, which is an act of personal handwriting, a 图章 is a fixed, unchanging mark. This distinction is crucial. While a signature's validity can be debated based on handwriting analysis, the impression of an official seal is considered definitive proof of authorization. This reflects a cultural value placed on tangible, verifiable symbols of authority. For artists and calligraphers, the placement and design of their personal seal is an integral part of the artwork itself, acting as a final, aesthetic touch and a mark of authorship.
The use of 图章 is not just historical; it is a vital part of modern Chinese life and business.
