《资治通鉴·晋纪·晋纪十》
他们听说我们离去了，对能够自己保全而感到高兴满足，还有什么功夫追击我军的后部，施行不利于我军的行动呢？
彼闻吾去，喜于自全，何暇追袭吾后，为吾不利邪！
When they hear that we have left, they will be happy and satisfied just to be able to protect themselves. How could they have the time or energy to pursue our rear forces and take any action that would harm our army?
