A seal, in an East and Southeast Asian context, is a general name for printing stamps and impressions thereof which are used in lieu of signatures in personal documents, office paperwork, contracts, art, or any item requiring acknowledgement or authorship. On documents they were usually used to print an impression using a pigmented paste or ink, unlike the wax impression commonly used in Europe.

The Qianlong Emperor, also known by his temple name Emperor Gaozong of Qing, personal name Hongli, was the fifth emperor of the Qing dynasty and the fourth Qing emperor to rule over China proper.
