Class hours refer to the learning time calculated by class hours. It is generally believed that both non-adult education and full-time university education are 40-minute classes.

Off-campus training generally adopts the consumption mode of paying first and then serving. Once the training institution closes down, it is very likely that the training fees paid in advance by students and parents will not be returned, and their own interests will be seriously damaged. Prepaid bank custody focuses on changing the situation that training institutions unilaterally control prepaid funds and changing the weak position of students and parents in training services.

By handing over the advance payment to a third party, that is, the bank for supervision and management, allocating funds to training institutions according to the progress of providing training services, and urging training institutions to fulfill their obligations according to the contract, the legitimate rights and interests of students and parents are effectively protected. Off-campus training institutions open the only special account for prepaid funds custody in qualified banks, and report it to the education authorities for the record within 3 working days from the date of opening the special account.

Under the guidance of the education authorities, a special account management agreement was signed with the custodian bank to separate the prepaid funds from the self-owned funds, and all prepaid expenses must enter the special account, so that all prepaid expenses can be managed by someone. In the case of abnormal closure of training institutions, the tuition fees of students who have not stopped classes can be fully refunded from the bank, which protects the interests of students and parents to the maximum extent.
