Outside Shaw Stadium is a tennis court, and the badminton court is inside the stadium. Of course, there is a charge inside, and the charge and reservation are written at the door. I forgot the specific price. Usually someone else books the venue, and I take a taxi. If we say free badminton courts, most of them should bring their own nets. There are dormitories facing the left-hand side of the main entrance of the dining hall, and there are also chemistry departments. You can go and have a look. . .
