《三国志·魏书·二李臧文吕许典二庞阎》
李通的亲戚属下都流着泪说： 现在我们孤立无援，独自守卫，被攻破是迟早的事，不如迅速投靠袁绍。 
通亲戚部曲流涕曰： 今孤危独守，以失大援，亡可立而待也，不如亟从绍。 
Li Tong's relatives and subordinates burst into tears and said: Now that we are isolated and helpless, guarding alone, it is a matter of time before we are breached. It is better to surrender to Yuan Shao quickly.
