《太平广记·卷一百二十·报应十九》
就在那一年，孝昭帝多次看见文宣帝变成各种妖怪到他面前要儿子，孝昭帝各种祈祷祭祀的方法都用尽了，最终还是没有使文宣帝走去而死。
其年，孝昭数见文宣作诸妖怪，就其索儿，备为厌禳，终不能遣而死。
In the same year, Emperor Xiaozhao saw Emperor Wenxuan transform into multiple monsters to come in front of him and asked for his son many times. Emperor Xiaozhao used various methods of praying and sacrificing, but he eventually did not make Emperor Wenxuan leave and he died.
