《汉书·传·卫青霍去病传》
汉朝轻骑校尉郭成等追了几百里，没有追上，俘虏右贤王属下小王十多人、男女人众一万五千多人、牲口数十上百万头。于是卫青率军回来。
汉轻骑校尉郭成等追数百里，弗得，得右贤裨王十余人，众男女万五千余人，畜数十百万，于是引兵而还。
The Han light cavalry captain Guo Cheng and others pursued for hundreds of miles, but did not catch up, capturing more than ten of the subordinate kings of the Right Xian King, more than 15,500 men and women, and millions of head of livestock. Wei Qing then led the army back.
