The gym cheated money, and the plaintiff sued for delaying work. Can I claim compensation from the defendant?

Of course. The Law of People's Republic of China (PRC) on the Protection of Consumers' Rights and Interests stipulates that if consumers are affected by businesses, they can ask businesses to compensate for lost time, and compensation for mental damage can be paid, that is, if the plaintiff sues for delaying work, they can ask the defendant for compensation. Gym refers to the place used for fitness, rehabilitation and exercise activities, with complete equipment, comprehensive fitness and entertainment programs, guidance of professional coaches and good fitness atmosphere.
