China etiquette rules?

The traditional rule of China people's communication is that courtesy is reciprocal, and courtesy is light on people's intentions. Please note that both of these statements have "courtesy" and both emphasize the need for "courtesy", but "courtesy" is not important. As the saying goes, sincerity is in the middle and outside, and the heart needs external forms to express it. It is necessary to bring some small gifts when sisters walk around each other during the Chinese New Year. Imagine: do you think it's interesting for several people to wipe their mouths after eating empty-handed?

The rules left by ancestors are the summary and refinement of life experience in interpersonal communication and an integral part of traditional culture. They are very precious and should be observed. It should be noted that if you don't pull the rules, will there be culture?
