《史记·七十列传·卫将军骠骑列传》
皇上听过汇报后，怕浑邪王用诈降的办法偷袭边境，于是就命令骠骑将军领兵前去迎接浑邪王和休屠王。
天子闻之，於是恐其以诈降而袭边，乃令骠骑将军将兵往迎之。
After hearing the report, the emperor was afraid that the King of Xiongnu would use the method of pretended surrender to attack the border, so he ordered the General of the Flying Cavalry to lead troops to greet the King of Xiongnu and the King of Xiutu.
