《汉书·传·李广苏建传》
苏武说： 我们父子无功无德，都是由于皇帝的提拔，才位列将军，爵至通侯，兄弟三人都为皇帝近臣，常愿为此肝脑涂地。
武曰： 武父子亡功德，皆为陛下所成就，位列将，爵通侯，兄弟亲近，常愿肝脑涂地。
Su Wu said: We father and son have no merits or virtues, It is because of the emperor’s promotion, that we have become generals, and viscount, we three brothers are close ministers of the emperor, we often wish to risk life and limb for him.
