What do you mean by learning to be an adult?

Etiquette means a series of norms. The reason why norms should be formulated, or the root of etiquette, is that people are social animals who live in groups. Group life inevitably needs to deal with various relationships between people and even between countries. The norm to deal with this relationship is etiquette. Being a man means that an individual has achieved fame and career achievements in society. Confucian culture mainly refers to "self-cultivation, keeping the family in order, governing the country and leveling the world". What is an "adult"? The explanation in Zhu Zhu's annotation "The Analects of Confucius" is: "Adults still have much to say." "Gentleman is useless" (politics 12), a gentleman is not just a person who does small things in one aspect, but a person who develops in an all-round way. So the adult here refers to a person who basically meets the requirements of having both ability and political integrity, and a person with all-round development.
