1. In case the gym is closed and the contract cannot be continued, the consumer can ask the merchant to cancel the prepayment contract, return the prepayment balance, and can ask the merchant to compensate for the loss. If the above communication fails, consumers should promptly complain to the Consumer Protection Committee, the Market Supervision Bureau and other relevant departments for consultation and mediation. If mediation fails, consumers can bring a lawsuit to the people's court where the gym is located or where the merchant is located with valid evidence.

2. Article 566 of the Civil Code: If the contract has not been performed after dissolution, the performance shall be terminated; If it has been performed, the parties may demand restitution or take other remedial measures according to the performance and the nature of the contract, and have the right to claim compensation for losses. Where the contract is terminated due to breach of contract, the creditor may require the breaching party to bear the liability for breach of contract, unless otherwise agreed by the parties.
