《资治通鉴·汉纪·汉纪五十六》
徐晃对曹操说： 袁氏兄弟还未被打败，未归降的诸城都在侧耳倾听，应该表彰奖赏这两个县的官员，为那些城作个榜样。 
徐晃言于操曰： 二袁未破，诸城未下者倾耳而听，宜旌赏二县以示诸城。 
Xu Huang said to Cao Cao: "The Yuan brothers haven't been defeated yet, and the cities which haven't surrendered are all watching and listening. You should reward the officials of these two counties as an example to the other cities."
