Aju (or Achu; Khalkha Mongolian: ; ) (1227–1287) was a general and chancellor of the Mongol Empire and the Yuan dynasty. He was from the Jarchud clan of the Mongol Uriankhai. His father was Yuan dynasty general Uriyangkhadai and his grandfather was Subutai, the honored general and Noyan of Genghis Khan.

Mujū Dōkyō (; 1 January 1227 – 9 November 1312), birth name Ichien Dōkyō, was a Buddhist monk of the Japanese Kamakura period. He is superficially considered a Rinzai monk by some due to his compilation of the Shasekishū and similar books of koans, but there is good evidence that he was also an eager student of the Tendai, Pure Land, and Hosso sects, and he is occasionally placed in the Shingon and Ritsu sects as well.
