《后汉书·列传·隗嚣公孙述列传》
如果蒙恩宽赦，更得洗心革面，则死骨不朽。 官吏们以隗嚣出言傲慢，请求把他儿子隗恂杀掉，帝不忍心，再派来歙到，以书信赐隗嚣说： 以前柴将军与韩信书说 ：陛下宽仁，诸侯虽有叛变后又回来的，还是恢复他们的位号，不加杀害。 
如遂蒙恩，更得洗心，死骨不朽。 有司以嚣言慢，请诛其子恂，帝不忍，复使来歙至氵幵，赐嚣书曰： 昔柴将军与韩信书云： 陛下宽仁，诸侯虽有亡叛而后归，辄复位号，不诛也。
If I am pardoned with grace, I must reform and return to the right path, then my mortal bones shall not perish. The officials thought that Wei Xiao’s words were insolent and asked to kill his son Wei Xun, however the emperor could not bear to do so, and sent Lai Xi to deliver a written message to Wei Xiao, which said: “In the past, General Chai wrote to Han Xin saying: His Majesty is generous, even the vassal states that rebel but later return, will remain their titles, and not be killed. Knowing that you, Wei Xiao, was a civil official and understood the principles of righteousness, this message was written for you. Explicitly, would be less respectful and brief, would make clarification difficult. If you halt immediately, as you did before when you sent your son Wei Xun to me, then you shall be able to obtain your entire rank and prestige, there will be great fortune for you. I am almost 40 years old, and have been in the army for 10 years, am tired of all this empty language and flattery. If you do not want to, you are excused from reporting back.” Wei Xiao knew that the emperor had seen through his cunning, and so he sent messengers to declare himself as Gongsun Shu’s vassal. The following year, Gongsun Shu made Wei Xiao the King of Shuoning, and dispatched soldiers back and forth, to show his support. In the autumn, Wei Xiao led 30,000 infantry and cavalry, and invaded Anding, reaching Yin, where Feng Yi led his generals to resist.
