What are the main etiquette of Confucianism? Specific point

For thousands of years, the spirit and cultural expression of etiquette have been everywhere, ranging from national strategy, war, the rise and fall of political power, folk culture, and even food, clothing, housing and transportation. Everywhere is the external expression of China immersed in the primitive ritual system. The ancients said, "Courtesy does not require all kinds of fields." If we go into the traditional rural areas of China, we can experience the lives of ordinary people, the words and deeds of ordinary people in China, family values, ethical customs, values and even life.

It can even be said that the Central Plains civilization at that time was different from the surrounding barbarians.

There are some Confucianists who specially explain etiquette, such as Guan Yi, Hunyi, Drinking in the Countryside, Shooting at Yi, Hiring Yi and Mourning Yi. Explain the appellations of Guan Shi Li, Hun Li, Xiang Yin Li, Xiang She Li, Da She Yi, Yan Li and Mourning respectively, which is most closely related to Yi Za.
