《金史·列传·卷十七》
我们用大军兵临江南，他们君臣一定是心破胆裂，将帅悲哀也没有时间了，即是说受弓伤的鸟空弓就可射下它。 
吾以大军临之，彼之君臣，方且心破胆裂，将哀鸣不暇，盖伤弓之鸟可以虚弦下也。 
We will use our army to approach the south of the Yangtze River, their monarchs and ministers will definitely be heartbroken and terrified, and their generals will not have time to grieve either. That is to say that injured birds can be shot down with an empty bow.
