《资治通鉴·宋纪·宋纪十五》
到了晚年，却猜疑、嫉妒、残忍、暴虐，迷信鬼神巫术，忌讳多端。无论言论、文书，对祸、败、凶、丧以及含混难辨的话和字有成百上千条，都加以回避，如有触犯，一定加以惩罚和诛杀。把  改成  ，因为  看起来象 祸 字。
及晚年，更猜忌忍虐，好鬼神，多忌讳，言语、文书，有祸败、凶丧及疑似之言应回避者数百千品，有犯必加罪戮。改 騧 字为 瓜 ，以其似祸字故也。
In his later years, he became suspicious, jealous, cruel, and tyrannical. He was superstitious about ghosts and witchcraft and had many taboos. Whether it was speech or documents, he avoided hundreds of words and phrases related to disaster, defeat, misfortune, mourning, and ambiguity. If he was offended, he would be punished and executed. Change  to   because   looks like the word   祸  .
