《史记·七十列传·西南夷列传》
在这个时候，巴郡、蜀郡、广汉郡、汉中郡开通西南夷的道路，戍边的士卒、运送物资和军粮的人很多。
当是时，巴蜀四郡通西南夷道，戍转相饟。
At that time, the prefectures of Ba, Shu, Guanghan and Hanzhong opened up access to the south-west Wei, and a large number of armed forces were deployed on the frontier, and officials were sent to transport supplies and armed forces.
