What is the significance of the idea of "the rule of etiquette" to the formation of traditional Chinese culture?

The rule of etiquette can be said to run through the core of the entire Chinese culture, and is the root of the Chinese feudal system. As for its significance, it can be said that it is the essence of traditional culture, but it is not necessarily perfect, and it can only be said that it is because in history, our ancestors did not invent anything better, and they just made do with what they had!

Today it looks like the list of sophistry is endless. Feudal legislation does not meet the requirements of modern society, and very much from the ugly and unpleasant. However, the state of the nation today is a copycat, the new did not learn, the traditional also lost. Some people say forward to continue to learn, some people insist on going back to the past, things are no longer good, but also better than nothing ah!

But I don't think it's possible to go back, the old things were abandoned in the first place, how can there be no reason? If he was perfectly adapted to the times, how could he have been abandoned? The new things did not learn well is not their own reasons? Is it all about learning from others? Who are you blaming for not learning the good things and learning the bad things? People, there is no firm sense of right and wrong, there is no firm conviction, why should we shirk our responsibilities, not I also soldiers also? People are sinful, no matter how ancient or modern Chinese or foreign the Mo so
