An embroided silk gold and silver thread rank badge of a crane, Qing dynasty 18th century.

Rank badges (also called rank insignia or Mandarin squares) were used in China during the Ming (1368–1644) and Qing (1644–1911) dynasties to demonstrate the wearer’s rank. In 1391 new clothing regulations directed court officials to wear decorative squares indicating their rank—birds for civil officials and animals for military officials. During the Qing dynasty rank badge design was regulated, and certain creatures were associated with specific ranks. Qing badges depict a representation of the universe with a landscape and a central creature, surrounded by clouds and facing the sun. The sun represented the emperor and this composition showed the official’s loyalty to him. An official’s wife wore rank badges that mirrored her husband’s. Rank badges are generally square or rectangular, although round examples exist.
