《贞观政要·卷二·论纳谏》
长孙皇后劝谏说： 从前齐景公因为马死了要杀人，晏子请求数说养马人的罪状： 你养的马死了，这是你第一条罪。
皇后谏曰： 昔齐景公以马死杀人，晏子请数其罪云： 尔养马而死，尔罪一也。
Empress Changsun advised him, saying: "In the past, Duke Jing of Qi wanted to kill a man because his horse had died. Yanzi asked to recount the stableman's crimes: The death of your horse is your first crime."
