佛祖統紀 32.35

32.35

During the Yongping era of Emperor Ming, Ban Chao was sent as an envoy to the Western Regions. Arriving at Shanshan, he beheaded the Xiongnu envoys. Terrified, the king of Shanshan offered his son as a hostage. Later, Ban Chao mobilized troops from various kingdoms to attack Shache and beheaded the king of Shule. He defeated the auxiliary king of the Yuezhi, brought to submission Qiuzi, Gumo, and Wensu, and beheaded the two kings of Yanqi and Weili. His awe shook the Western Regions, and more than fifty kingdoms sent hostages to submit as internal vassals (from Ban Chao's biography in the *History of the Later Han*).
