It didn't work. It didn't work. The gym died, and the boss changed. According to the relevant laws of the Civil Code, contracts are relative. Consumers apply for membership cards of health clubs. Before the advance payment in the membership card is used up, there is a contractual relationship between the fitness club and the consumer, and the consumer enjoys the right to enjoy fitness services in the club according to law. Second, as a fitness club, it belongs to the company, and its members form a consumer service contract relationship with the fitness club. If it belongs to individual industrial and commercial households, it forms a contractual relationship with the boss. The fitness club is a company. If the owner changes, members can still claim the right to continue fitness consumption from the club. If rejected, they can ask for a refund. The fitness club is a person, and now it has a new boss. In principle, members cannot claim rights from the new boss. According to the principle of relativity of contract, they can only claim their rights from the original boss and ask for a refund.
