In 121 BC, Emperor Wu of Han sent his general Huo Qubing to attack Xiongnu, dealing a great defeat on the Xiongnu. In the campaign, Huo killed the Princes of Zhelan and Luhou, as well as 8,900 Xiongnu soldiers, while capturing the Prince of Hunye's son, chief assistant, and a number of officials, as well as golden statues that the Prince of Xiutu had forged to use to worship heaven. Yizhixie Chanyu was greatly displeased, and was considering summoning the Princes of Hunye and Xiutu to execute them. The princes, in fear, plotted to defect to Han. When Emperor Wu sent Huo to accept their surrender, the Prince of Xiutu changed his mind and tried to back out of defecting. The Prince of Hunye killed him and surrendered to Han, along with the region that he controlled.
