Legal analysis: it is impossible for training institutions to train their own teachers. For them, the most efficient way is to spend twice the salary to dig high-quality teachers from public schools. Good teachers go to training institutions, and parents have to spend several times the tuition. In order to meet good teachers, educational resources have become distributed according to family circumstances, so rich people monopolize high-quality educational resources, so the state should stop off-campus training.

Legal basis: Anti-monopoly Law of the People's Republic of China.
