《资治通鉴·汉纪·汉纪四十一》
如今他们的势力正在高涨，我们难于以强力取胜，兵不厌诈，请允许我放开手脚去对付他们，只不要有所约束阻碍即可。 
今其众新盛，难与争锋；兵不厌权，愿宽假辔策，勿令有所拘阂而已。 
Now their power is growing and we find it hard to win by force. It is said that in war, deception is tolerated. Please allow me to deal with them freely, and do not impose any constraints or obstacles.
