Why do parks and gyms in Beijing charge?

The school gymnasium has always been managed by the property tendered by the school instead, and in the previous management process, our students and teachers complained bitterly. Let's talk about the badminton court in the gymnasium. In the past, everyone could only book two sessions a day, with a total time of two hours. And many times, in order to find time to play badminton, we have to make an appointment until twelve o'clock in the evening, otherwise there will be no venue reservation. What often happens is that you finally grab a stadium to play, and then you find that no one has gone to the stadium you originally booked. I don't know those reserved courses didn't go or cancel.
