《资治通鉴·宋纪·宋纪十》
有人劝朱之加快追击的速度，朱之说： 鲁秀是一名骁勇将士。野兽在走投无路时，就要不顾一切地抓人咬人，我们不能急迫追击 。
或劝修之急追，修之曰： 鲁秀，骁将也；兽穷则攫，不可迫也。 
Someone advised Zhu Zhi to speed up the pursuit, Zhu Zhi said: Lu Xiu is a brave warrior. When a beast is desperate, it will bite and scratch people regardless of everything. We mustn't pursue him in a hurry.
