Бань Чао
In 25 CE it was recorded that Shanshan was in league with the Xiongnu. In 73 AD, the Han army officer Ban Chao went to Shanshan with a small group of followers, which was also receiving a delegation from the Xiongnu. Ban Chao killed the Xiongnu envoys and presented their heads to the King, after which King Guang of Shanshan offered his allegiance to Han.
