《后汉书·列传·南蛮西南夷列传》
周公说： 没有给他人施加恩德，那么有贤德的人就不享用他人的礼品；政令没有在那裹推行，有贤德的人就不将那裹的人作为臣民。
公曰： 德不加焉，则君子不飨其质；政不施焉，则君子不臣其人。
The Duke of Zhou said: When one has not shown kindness to another, a person of virtue will not accept their gifts; when one's writ does not run in a place, a person of virtue will not take its people as subjects.
