Coaching/Training/Playing in Beijing

[Cheer]

Hi, I'm a Singaporean going over to Beijing for the whole month,
But I'm so troubled where can I find group to play with after work and during the weekends. Preferrably mix-doubles ...

Can any kind soul out there advise me on where I can join for a group coaching/training programme? Any good recommendation out there?

And where I can join for a regular games ??

Thanks for any reply.
