You can go to Ritan Tennis Hall or the R&F Club in Shuangjing. However, the R&F club needs to apply for membership, but I forgot the annual membership fee ... I learned it at the Beijing Club, and I am also a member. Individual membership fee10.5 million, and company membership fee10.8 million. Besides, I have to pay 1.600 every month. The advantage of membership system is that the venue is free and the coaching fee is 20%, but I can't get in without being a member.
