《资治通鉴·晋纪·晋纪二十二》
张说： 如果一定像你们所说的那样，秦国的威力德行所向无敌，为什么不先去夺取长江以南，那样天下就全归秦国所有了，征东将军为什么要辱赐恩命于我们呢！ 
瓘曰： 必如君言，秦之威德无敌，何不先取江南，则天下尽为秦有，征东何辱命焉！ 
Zhang said: If it is really as you said that the power and virtue of Qin are invincible, why don’t you first go and seize the land south of the Yangtze River, so that the whole world would belong to Qin? Why did the General of the Eastern Expedition bestow this honor on us?
