Although, he first shared with Ayurbarwada the tutorship of the Confucian scholar Li Meng, he apparently was little affected by Confucian culture. He transferred Harghasun to Mongolia as the grand councillor of the left wing of Branch secretariat of Lin-pei despite his great contribution. Khayishan heavily relied on his retainers and commanders he had brought from Mongolia. He gave key posts to them and favored non-Mongol corps including the Kipchak, the Asud (Alans) and the Qanglï. In contrast, he did not reward abundantly the Khunggirad faction who had carried out a coup against Bulughan. Because Tula said something suspicious in rage, Khayishan suspected that he had a further object, and had him tried and put to death.
