goods. He issued new bills (Jiaochao) called Zhida-yinchao () to replace Zhiyuan-chao (). His anti-inflation plans did not achieve adequate results in his short reign, and dissatisfied Han Chinese officers and commoners. He attempted to push through a new nonconvertible silver currency but was defeated by public resistance. 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. Khayishan greatly favored Buddhism, so that he ordered the Tibetan Lama Chogdi Osor to translate the sacred books of Buddha. When the Buddhist monks made mistakes except in cases affecting the Yuan dynasty, he refused to punish them. A law was passed that whoever struck a Lama should lose his tongue, but Ayurbarwada repealed it as entirely contrary to precedent. However, Khayishan was the first Khagan to tax the lands held by the Buddhist monks and the followers of Taoism, hitherto exempt. In order to reduce the cost of supporting the Yuan bureaucracy, he issued an order in 1307 to dismiss the supernumeraries and to bring total number of officials in line with the quota that had been set by his uncle Temür Khan. The order produced no practical results; the number of bureau's chief officials jumped from 6 in Kublai's reign to 32. He also had the building of court officials and a new palace city built at Dadu and Zhongdu (the ruins of Zhongdu in Zhangbei County can be seen until today). In 1308 the Goryeo king Chungnyeol of Korea died, and Khayishan sent a patent for his successor Chungseon. That year Chapar and other princes of the Khanate of Ögedei came to Khayishan with their submission, permanently ending the threat against the Chagatai Khanate and the Yuan dynasty by Khaidu's sons. During his reign, the Yuan completed the subjugation of Sakhalin, forcing
