Why are the ancient feudal hierarchy and feudal ethics laws regarded as "heaven"?

Since the order and stability of "human relations" is the basis of maintaining the harmony and social stability of the people all over the world, the feudal hierarchy and feudal ethics are naturally regarded as "heaven" and "classics", which are the same principles that families, countries and the world should rely on, and thus naturally become the political program and guiding principles for border control. According to this principle, "harmony", "equality" and "security" are the normal ways. Because they are hard-won, they should be cherished and pursued hard, while conflicts and contradictions are abnormal and should be avoided. Therefore, there must be accommodation and mutual understanding based on ethical principles for the "four foreigners" who belong to the same "one body" and "one family", not just naked control and conquest.

The responsibility of politicians is to uphold and maintain harmony, and to the frontier and even the outside world, we should take "the harmony of all nations" as the criterion, and finally realize the ideal of "ruling the country by political virtue and demonstrating courtesy and righteousness".
