All primary schools in Beijing have free badminton courts. At present, the venues of primary schools are basically completely open, and some residents nearby can go to these primary schools to play badminton. The primary school playground in Beijing is relatively small, and playing badminton has certain limitations, but it is really a free venue.
At present, all parks in Beijing have opened badminton courts for free. Generally, as long as it is a state-owned park, there can be some small badminton courts, as long as the equipment is poor, but if it is for leisure and entertainment, the air quality is better.
Badminton courts in most stadiums in Beijing will also be open for free, but the venues of these stadiums depend on the time. Sometimes it is free, sometimes it is charged. The specific free opening hours need to be consulted according to different months, and there is no fixed time. But these venues are better, and playing badminton will be more suitable.
In addition, some universities in Beijing have some venues for fees, and the conditions for playing badminton will be relatively better, but the price is not very high. For example, in Beijing University of Political Science and Law, it costs 10 yuan an hour to get a membership card, but it costs 15 yuan without a membership card. Where to play badminton requires an appointment, and the situation in other universities is similar. If you have high requirements for playing badminton, you'd better go to the university venue.
