《后汉书·列传·南匈奴列传》
夏天，刚投降的一部首领阿族等人反叛，胁迫呼尤徽，想要他一道离开，呼尤徽说： 我已经老了，蒙受汉的恩德，我宁愿死也不能跟你们走！ 
夏，新降一部大人阿族等遂反畔，胁呼尤徽欲与俱去。呼尤徽曰： 我老矣，受汉家恩，宁死不能相随！ 
In the summer, one of leaders of the new arrivals, Azhu, and others rebelled, put pressure on Hu You, and wanted him to leave with them, but Hu You said: I am already old, and have received great kindness from the Han, I would rather die than go with you!
