As started by "keyulian" about finding a venue for a Gymnastic gym. (http://www.thebeijinger.com/forum/2006/12/05/Gymnasticsacrobatics-classe...)

I'm interested into finding a venue or place like this. Although I know that there a lot of Chinese Acrobatic Schools but my situation is the same keyulian.
Just dropping in from time to time to practice some acrobats. In my case is Parkour.

To top with that, I do not want any people suggesting to find an ex-acrobatic instructor because I'm not interested on getting instructed, I'm interested in the place where I can bring in my friends and practice from time to time.

Gymnastic Gym such as foam pits, high beams, trampolin. Where there's space to allow you to jump around.
I do not mean a place to lift weights, ride bicycles or treadmill.

Also, it will be nice if it welcomes foreigners. But I'm fine if they don't.
