"Joining" is a franchise in law. When signing a contract, you should abide by the provisions of the law on franchising. If the franchisee does not actually use the operating resources of the other company, he may request to terminate the contract according to law and refund the franchise fee according to the cooling-off period. In this case, the termination of the contract does not constitute a breach of contract. If negotiation fails, you can entrust a lawyer to sue or arbitrate!
If the franchisee did not participate in technical study after signing the franchise contract, did not accept site selection services and equipment and materials, and had enjoyed the cooling-off period before opening the business, he can bring a lawsuit to the court to defend his rights according to the cooling-off period, request to terminate the contract and refund the franchise fee.
