Chinese Seal(印章) is a quintessential symbol of traditional Chinese culture, Throughout history, emperors used imperial jade seals to demonstrate legitimate imperial power, government offices applied official seals on documents to prevent forgery, while literati and artists used them to sign inscriptions and enhance the beauty of calligraphy and paintings. Traditional seals were typically crafted from hard materials such as jade, hardwoods, ox horn, bronze, or gold. The seal face was engraved with characters including names, institutional names, official titles, or famous sayings, primarily in square or circular shapes, and carved in either relief (Zhuwen) or intaglio (Baiwen). Ancient China's seal culture was adopted by neighboring East Asian countries like Japan and Korea, where they developed their own distinctive seal systems.

In modern society, seals remain indispensable in many contexts. In government and business, important documents such as contracts and agreements still require seal impressions to be legally valid. On a personal level, seals are widely used for banking and administrative procedures, while also enduring as a personal artistic hobby—seal engraving (Zhuanke).

To promote traditional Chinese culture, BarcodeOcean offers an online seal generation tool.
