👉 The impressed weapon, also known as the Impressed Seal or Impressed Seal of the Great Seal, is a distinctive feature of Chinese imperial seals and documents. It involves intricate designs and inscriptions that are impressed onto the seal using a metal stamp or engraving tool, creating a raised, three-dimensional effect. This technique was primarily used for official documents and seals issued by the emperor or high-ranking officials, emphasizing their authority and authenticity. The impressed design not only served a practical purpose of ensuring the document's legitimacy but also showcased the skill and craftsmanship of the artist who created it, often incorporating symbolic elements that conveyed the status and power of the issuing entity.
