《北史·列传·卷一》
高祖又喊彭城、北海二王，让他们入座，并说： 她过去是你们的嫂嫂，从今以后便是别人了，你们只管进来，不必回避。 
高祖乃唤彭城、北海二王令入坐，言： 昔是汝嫂，今便他人，但入勿避。 
Gaozu also shouted to the two kings of Pengcheng and Beihai, asking them to take their seats, and said: “She used to be your sister-in-law, but from now on she is someone else. Just come in, you do not need to be shy.”
