《北史·列传·卷三十三》
普惠答道 ：过去淮南王刘安因为叛逆被处死，汉文帝还封赏他的四个儿子，这是骨肉之情不可离弃、关系亲密的缘故。我见咸阳王、京兆王都是皇子皇孙，仅因一时犯罪，就自己种下祸根，永远沉沦下僚，再也不被起用，难道不应复兴衰败的贵族旧戚吗？ 太后说 ：你说的很有道理，应当让公卿大臣们广泛议论一下。 
敬绍颇览书传，微有胆力，而奢淫倜傥，轻为残害，又见天下多事，阴怀异图，欲杜绝四方，擅据南郑。令其妾兄唐昆仑扇搅于外，聚众围城，敬绍谋为内应。
Pu Hui replied: "In the past, the King of Huainan, Liu An, was executed for rebellion, but Emperor Wen of Han still rewarded his four sons. This was because the bond between flesh and blood cannot be severed or broken. I have seen that the King of Xianyang and the King of Jingzhao are both Imperial Princes and Grandsons of the Emperor. They have only committed temporary crimes and have themselves sown the seeds of their own misfortune. They have been forever demoted and will never be re-employed. Doesn't this fly in the face of the need to restore fallen nobles and old relatives?" The Empress Dowager said: "What you say is reasonable. We should have the high officials and nobles discuss it widely."
