《后汉书·列传·杨李翟应霍爰徐列传》

奉以田氏微贱，不宜超登后位，上书谏曰： 臣闻周纳狄女，襄王出居于郑；汉立飞燕，成帝胤嗣泯绝。
Ying Feng believed that Ms. Tian was of humble background and should not be elevated to the position of empress, so he submitted a letter of advice: I heard that during the Zhou Dynasty, Di girls had been accepted, and King Xiang had to live in Zheng; Han established Zhao Feiyan as empress, and Emperor Cheng was destroyed in the end.
