The expression is from Xunzi (313?-238BC). It aims to raise the status of social norms so that they can fully exert their role. Xunzi believed that social norms regulate human behavior and are a yardstick for judging right and wrong, and they underpin the governance of a country. Humans by nature seek external desires, and do not have the inherent quality of acting for the good. So to avoid rivalry and disorder caused by unrestrained desire, it is necessary to educate people in social norms so that they will willingly follow such norms.

The ruler who observes social norms and respects men of virtue will be able to keep his country united. He who adheres to laws and has compassion for his people will rise above other rulers. In contrast, pursuit of selfish-gains and cheating can endanger the country, and power manipulation, playing fast and loose and deception can only destroy the country. (Xunzi)
