Legal analysis: if the training institution does not refund the money, it can negotiate with the institution for a refund, and both parties make concessions to reduce the consumption of time and money cost brought by litigation. If no agreement can be reached, a lawsuit can be brought to the court to explain the losses caused by the institution's breach of contract, request the court to judge the institution to refund the deposit or tuition fee, and may require it to compensate part of the liquidated damages. The prosecution should pay attention to the statute of limitations.
