1. Contract restraint: In housing training institutions, you can restrain your behavior by signing contracts. For example, you can sign a contract with the institution, stipulating that you need to finish the course on time, take the prescribed exams, and you must not do anything that violates the regulations of the institution during the training. If you break the contract, you will be fined or disqualified.

2. Discipline: Accommodation training institutions usually make their own discipline regulations, such as not allowing students to do things unrelated to the course during class hours and not allowing students to eat in the classroom. If they violate these regulations, they will be punished or warned.

3. Administrative constraints: Housing training institutions will be bound by relevant administrative agencies. For example, government departments may supervise the review. If it is found that there are irregularities or improper behaviors in housing training institutions, it can be reported to the relevant administrative organs.
