《新唐书·列传·卷一百零八》
韩偓说： 皇上困在东宫时，天阴有雾，辉王听见乌鸦叫声后说 ：皇上和皇后被关押，乌鸦的叫声也是悲伤的。 
偓曰： 陛下在东内时，天阴雺，王闻乌声曰： 上与后幽困，乌雀声亦悲。 
Han Chan said: "When Your Majesty was imprisoned in the East Palace, the sky was gloomy and foggy. After King Hui heard the crow cry, he said: 'The emperor and the empress are imprisoned, and even the crow's cry is one of sadness.'"
