(1) Why does "ceremony" occupy a core position in China culture?

1. "Rite" is one of the core contents of Confucius' Confucianism. Confucius emphasized order, and everyone in the whole society abides by order, so the society will be stable and United, and "ceremony" is the ultimate way to realize this order. People communicate with each other through this norm, establish social order, and cultivate people's habit of obeying order through "ceremony". Later, as Confucianism became the state religion of China, etiquette also entered the core position of China culture.

50 million overseas Chinese mainly live in Southeast Asia. Japan, North Korea, South Korea and Vietnam in Southeast Asia are all countries in the circle of Chinese civilization, so the Spring Festival has become the same festival in East Asia and Southeast Asia. In recent years, with the continuous development and strength of China and the increase of overseas Chinese, many European and American countries have also designated the Spring Festival as a public holiday.

4. Confucianism in China is mainly concerned with politics. As long as other religions don't compete with him for the dominance in the political field, Confucianism generally won't fight back (events such as Wang Chong's extermination of Buddhism in the Southern Dynasty and Han Yu's expulsion of Buddhism in the Tang Dynasty are all Confucian counterattacks against religious interference in politics), what's more, Confucianism doesn't consider itself a religion, but a theory and idea, and other religions are just tools for governing the country-people can naturally live in harmony with many religions without competing with tools.

After a long period of running-in, China generally manages the country and the people with Confucianism, supplemented by Buddhism and Taoism.

Islam is a minority religion, and the Han people don't believe widely and have little political influence on China, so Confucianism doesn't reject it.

If Christianity is only a religion and does not enter politics, I believe Confucianism doesn't matter to him.
