《左传·成公·成公十六年》
人民生活优厚，道德就端正；举动有利，事情就合于节度，时宜合适，生产就有所成就；这样就能上下和睦，相处没有矛盾，有所需求无不具备，各人都知道行动的准则。
民生厚而德正，用利而事节，时顺而物成。上下和睦，周旋不逆，求无不具，各知其极。
When the people's lives are enriched, their morals are upright; when their actions are beneficial, their affairs are in order, and when the time is right, they achieve success; in this way they can be harmonious and live without conflict, they have everything they need, and everyone knows the rules of conduct.
