《汉书·传·匡张孔马传》
一般说，教养百姓，如《孝经》所说： 陈述道德仁义给他们听 ， 公布好坏标准给他们看 ，观察他们的失误而明确行为规范，因此行动就会和睦相处，抚慰就会安宁无事。
盖保民者， 陈之以德义 ， 示之以好恶 ，观其失而制其宜，故动之而和，绥之而安。
Generally speaking, educating the people should be like what the "Book of Filial Piety" says: Tell them about morality and righteousness, show them the standards of good and evil, and observe their mistakes to establish norms of conduct, so their actions will be harmonious and they will be peaceful and untroubled.
