The name Paiza or Paizi or Gerege

My new project. The name Paiza or Paizi or Gerege (Middle Mongolian: Гэрэгэ, Mongolian: Пайз, Persian: پایزه pāiza, Chinese: 牌子 páizi) is a tablet of authority for the Mongol officials and envoys. This enabled the Mongol nobles and officials to demand goods and services from civilian populations.
Project for the Museum of Eastern province.
