《战国策·韩三·客卿为韩谓秦王》
韩国的一位客卿为韩国对秦王说： 韩珉议论政事，只了解自己的国君不了解别国国君，只了解自己的国家而不了解其他国家。
客卿为韩谓秦王曰： 韩珉之议，知其君不知异君，知其国不知异国。
A guest of South Korea said to King Qin for South Korea: Han Min discussed political affairs and only understood his own monarch but not other monarchs. He only understood his own country but not other countries.
