Motocross in Shunyi?

Hello, Im new on this forum, tried to find the info in previous post but didnt manage..

Im looking for a motocross track around Shunyi. So far we have been running around on the riverbeds and the small tracks along the river, but now these tracks has bocome golf cources...

We dont need (cant handle..) big jumps etc, but would like to find a track that isnt totally flat where we can spend a few hours in the weekends.

Anyone who knows where to go?

All the best/Anders
