Hi Narra, welcome to Rctech.

You can find some RC shops on http://www.rcfans.net/ It's in Chinese but its still a good place to look....... They should have some racing happening in Beijing somewhere but out of my expertise.

Another place to ask would be to look on Taobao and ask one of the sellers there some questions as to where the tracks are. You can try them in English (some speak English) and if all else fails then use a translator... They are usually pretty helpful there.. There are a few On road tracks around China but its usually local knowledge that helps find them.

Good luck........ and remember to report back with you progress
