If you graduate from the Music Department of the Normal University, there should be at least 50 students in each class. If there are more students, you will have more money.
If you graduated from the piano department, private school students didn't learn a lesson 100, at least they haven't heard of it.
If you are a piano teacher, there are generally at least 200 to 300 students in private schools. If you are looking for an old professor with a single class or two, the cost will be more expensive. However, it is another discussion for students. It is estimated that tens of thousands a month is no problem. As long as the teaching is good, students will keep coming.
But the art school outside is dark and sparring is very low. We call it squeezing coolies. Many of my classmates were forced to stay with them for an hour when they were in their twenties and thirties, and the teachers were about fifty or sixty years old. Therefore, if you have resources, the money you work alone will come faster.
Four ways to make money:
1 piano teaching
Recording of piano performance in small occasions
3 composition and arrangement
Performance on four major occasions
