《孔子家语·论礼》
孔子说： 作为民的父母，必须懂得礼乐的来源，达到 五至 实行 三无 ，以此施行于天下。四方出现祸患，必定预先知道。这样的人就可以称得上民的父母了。 
孔子曰： 夫民之父母，必达于礼乐之源，以致五至而行三无，以横于天下，四方有败，必先知之，此之谓民之父母。 
Confucius said, "As parents of the people, one must know the origin of ritual and music, achieve 'wu zhi', practice 'san wu', and use these to govern the world. When disasters appear in the four directions, one must know about them beforehand. Such a person can be called the parents of the people."
