《资治通鉴·宋纪·宋纪十六》
冯太后因为淫乱行为，害怕别人对自己讥讽议论，官员言谈中只要一句话被疑为对她的讽刺，就立即诛杀。
太后自以失行，畏以议己，群下语言小涉疑忌，辄杀之。
Because of her licentious behavior, the Empress Dowager Feng was afraid that people would gossip about and criticize her. Whenever an official was suspected of mocking her in conversation, he was immediately executed.
