How should a 4-year-old photographer go?

You should either be promoted to middle management, and occasionally give guidance to new people for training. Either go to a photography school as a teacher, which is not too tiring, and the salary is not bad, but there must be works with good reputation. Unless you have connections to go to a public school like Beijing Film and Chinese Opera. Generally, teachers are hired by training schools based on their qualifications and works.

there is another way: freelance photographer. Set up your own studio. Rent a house, get a license, open an account on various platforms, operate the network, and create a personal IP. It's all up to you.
