《汉书·传·匈奴传上》
于是汉天子便下诏令派边塞上的骑兵驻扎在要害地方，派大将军军监治众等四人率领五千骑兵，分做三路，分别出边塞几百里，各抓获匈奴几十人回来了。
于是天子诏发边骑屯要害处，使大将军军监治众等四人将五千骑，分三队，出塞各数百里，捕得虏各数十人而还。
The Han emperor then issued an edict to order the cavalrymen of the border to set up in vital areas, and sent four men, including the Grand General Junjianzhizhong, to lead five thousand cavalrymen, and divided into three groups,それぞれが国境から数百キロも出て、数10人の匈奴を捕らえて帰って来た。
