The following suggestions are for your reference. You log in first, and then find a group. Enter your area, such as Jinshan table tennis, and you will find the table tennis group in Jinshan. Then, you apply to join this group. Then, you can 1, consult group friends and get information, such as whether the table tennis hall in Jinshan National Fitness Activity Center is free, the opening hours and prices of the hall, and the training (coach? Sparring? Price? Location) and so on, the location and telephone number of specialty stores, the information of various clubs, all kinds of game information (golfers often participate in games), the situation of masters, the configuration of rackets and so on. 2. The group friends you know can invite them to play ball together. That's how I found the golfers nearby.
