《新唐书·列传·卷五十七》
用古代亡国之君的办法治国没有不灭亡的。人要害病了，一定会先不想吃鱼和肉；国家将要灭亡，必定先不认为忠言直谏好。
人将疾，必先不甘鱼肉之味；国将亡，必先不甘忠谏之说。
No country will not perish if it is governed by the methods of the ancient perished kings. When people are about to get sick, they will definitely not want to eat fish and meat first; when a country is about to perish, it will definitely not consider loyal advice as good first.
