《史记·七十列传·匈奴列传》
匈奴侦察骑兵到达雍地的甘泉宫。于是汉文帝用中尉周舍、郎中令张武做将军，派出千辆兵车，十万骑兵，驻守在长安旁边防御匈奴的侵扰。
於是文帝以中尉周舍、郎中令张武为将军，发车千乘，骑十万，军长安旁以备胡寇。
The Xiongnu reconnaissance cavalry reached Ganquangong in Yongdi. So Emperor Wen of the Han Dynasty used the Lieutenant Colonel Zhou She and the Gentleman-in-Waiting Zhang Wu as generals, and sent out a thousand chariots and 100,000 cavalrymen to garrison near Chang’an to defend against the Xiongnu invasion.
