《北史·列传·卷三十九》
太后打了他一百多杖，不久死去。太后哭得十分悲哀，说 ：我恐怕你不成才，才打你，谁想到你带着创伤死去了！ 
后事发，王氏赐死，诏杖凝一百，其愚如此。
The empress dowager beat him more than a hundred times and he died shortly afterwards. The empress dowager cried very sadly and said: I beat you because I was afraid you wouldn't be successful, who would have thought that you would die from your injuries ?!
