This fee is mainly used to identify students and ensure that the fees paid by customers can be guaranteed. In the game studio, trainers usually charge customers a certain deposit to show their professional ability and credibility.
The role of this deposit is to ensure that customers can get certain protection when choosing a substitute trainer and that the substitute trainer can complete the game task according to the agreed requirements. For some difficult game tasks, the trainer may ask customers to pay a higher deposit to ensure that they can get enough rewards. However, if the customer fails to complete the game task as agreed, or the trainer fails to complete the game task as agreed, the deposit can be used as liquidated damages.
