《资治通鉴·汉纪·汉纪六十》
如今豺狼挡在路上，却先去捉狐狸，人们会说殿下避强攻弱，进攻谈不上勇，撤退也谈不上仁慈。
方今豺狼当路而狐狸是先，人将谓殿下避强攻弱；进不为勇，退不为仁。
Now there are wolves standing in the way, but I want to go to hunt foxes. People will say that Your Majesty is afraid of the strong and persecuting the weak. You can't be called brave when you attack, and you can't be called benevolent when you withdraw.
