The concept of a seal as a mark of authority and identity is deeply rooted in Chinese history, dating back thousands of years. Emperors used imperial seals to sign edicts, and scholars used them to mark their personal collections and artwork. This tradition continues today, embedding the 私章 with a sense of formality, history, and seriousness that a simple handwritten signature often lacks.
While digital signatures are becoming more common, the physical 私章 remains essential in many aspects of life.
