《资治通鉴·汉纪·汉纪五十七》
曹操的军队远道而来，已经疲惫。听说在追赶刘备时，轻骑兵一天一夜奔驰三百余里，这正是所谓 强弩射出的箭，到了力量已尽的时候，连鲁国生产的薄绸都穿不透 。
曹操之众，远来疲敝，闻追豫州，轻骑一日一夜行三百馀里，此所谓 强弩之末势不能穿鲁缟 者也。
However, Cao Cao's army has come a long way and is very weary. I have heard that when he pursued Liu Bei, his light cavalry covered a distance of three hundred li in one day and a night. This is what is meant by “a strong bow with which one begins to shoot very fast, but the force soon exhausts itself, so that it will not pierce even a film.”
