"Pei Zun, the Administrator of Dunhuang, wrote saying that foreigners should not be allowed to employ such great authority and that these decrees would cause the kingdoms to despair. An Imperial decree then ordered that the seal and ribbons of “Protector General” be recovered, and replaced with the seal and ribbon of “Great Han General.” Xian's envoy refused to make the exchange, and (Pei) Zun took them by force. Consequently, Xian became resentful. Furthermore, he falsely named himself “Great Protector General,” and sent letters to all the kingdoms. They all submitted to him, and bestowed the title of Chanyu on him. Xian gradually became arrogant making heavy demands for duties and taxes. Several times he attacked Qiuci (Kucha) and the other kingdoms. All the kingdoms were anxious and fearful. In the winter of the twenty-first year (45 CE), eighteen kings, including the king of Nearer Jushi (Turpan), Shanshan, Yanqi (Karashahr), and others, sent their sons to enter the service of the Emperor and offered treasure. As a result, they were granted audience when they circulated weeping, prostrating with their foreheads to the ground, in the hope of obtaining a Protector General. The Son of Heaven, considering that the Middle Kingdom was just beginning to return to peace and that the northern frontier regions were still unsettled, returned all the hostage princes with generous gifts. At the same time, Xian, infatuated with his military power, wanted to annex the Western Regions, and greatly increased his attacks. The kingdoms, informed that no Protector General would be sent, and that the hostage princes were all returning, were very worried and frightened. Therefore, they sent a letter to the Administrator of Dunhuang to ask him to detain their hostage sons with him, so that they could point this out to the [king of] Suoju (Yarkand), and tell him that their young hostage sons were detained because a Protector General was to be sent. Then he [the king of Yarkand] would stop his hostilities. Pei Zun sent an official report informing the Emperor [of this proposal], which he approved. In the twenty-second year (46 CE) Xian, aware that no Protector General was coming, sent a letter to An, king of Shanshan, ordering him to cut the route to the Han. An did not accept [this order], and killed the envoy. Xian was furious and sent soldiers to attack Shanshan. An gave battle but was defeated
