《资治通鉴·梁纪·梁纪十九》
今天如想坚守城池则储存粮食的道路已经断绝，想作战则遗笑千古。无缘无故被俘受缚是我无法接受的，我还是逃往长江下游避避锋头吧。 
今日欲守则交绝粮储，欲战则取笑千载，不容无事受缚，当于下流避之。 
Today, if I want to defend the city, the road to food supplies has been cut off; if I want to go to war, I will be laughed at by all generations. It is unacceptable for me to be captured and bound for no reason. I'd better flee to the lower reaches of the Yangtze River to avoid the limelight.
