《元史·列传·卷六十三》
古人言：百姓的利害祸福，是国家的大事，其他人看到听到，但可不管，只有宰相能执行，执行得好坏谏官必须评论。
古人有言曰：生民之利害，社稷之大计，惟所见闻而不系职司者，独宰相得行之，谏官得言之。
The ancients said: The well-being and disasters of the people are major events of the country. When others see or hear about them, they can ignore them. Only the prime minister can carry out the executive orders. Whether the prime minister does the job well or not, the諫官 (諫官 was an official who made suggestions to the emperor) must make a comment.
