If you are a junior table tennis fan, you can find a table tennis board in any large stationery store. If you are tall, you can't hit those boards. For example, if you want to buy a butterfly racket, you have to go to specialty store. There seems to be no one in the university town. The nearest one is the one directly opposite the school gate of Jinshan No.3 Middle School: Mo Lifeng Sports sells professional table tennis rackets and butterfly rackets.

Just to be clear, I'm not a trustee. I bought it there.
