The number of the Tibetans in the administration gradually increased. The Khon family of Tibet was honored, and one of them became an imperial son-in law in 1296. Temür reversed his grandfather's anti-Taoist policy and made Taoist Zhang Liusun co-chair of the Academy of Scholarly Worthies. In 1304, Temür appointed the Celestial master of Dragon and Tiger Mountain as head of the Orthodox Unity School. He banned sales and distillation of alcohol in Mongolia in 1297, and the French historian René Grousset applauded his activity in the book, "The Empire of Steppes".
