《汉书·传·窦田灌韩传》
太后高兴地说： 我要替他向皇上解说， 解释以后，皇上的心才开解，而且摘下帽子向太后谢罪说： 我兄弟间不能互相劝教，竟让太后您操心了。 
言之，帝心乃解，而免冠谢太后曰： 兄弟不能相教，乃为太后遗忧。 
The Empress Dowager said happily: I will explain it to the Emperor for him. After she had explained, the Emperor's heart was relieved, and he removed his hat and apologized to the Empress Dowager, saying: I could not advise my brother and thus have worried you, the Empress Dowager.
