That's not true. I spent some time in the tutor department before, and I know it better. Personal information registration is free. If you have a tutor, you have to pay 50 yuan money first. Try teaching for two weeks, and if you decide to continue teaching, you will quit 20 yuan. If it fails, 50 yuan will give a full refund.

Because what can I say? As an organization of the school, charging parents makes people feel like a tutor outside. If there is no charge, there is no source of income. The school does not allocate funds for work-study programs, so it has to charge students. This is my understanding, I hope it will help you ~ ~
