Many table tennis halls have short-term training courses, but they are held from time to time. Sometimes they will post training notices at the door and start classes when there are enough people. Last time I watched it in the stadium west of the teaching field, 600 yuan/period seemed to last for a month and a half. There are also days and nights, Qing Palace, Warriors Table Tennis Club and so on. Olongbao will be relatively expensive, but the environment is good. It's up to you.
