Check out Fly and Avenue & Son in Shanghai. I think Jeff from Fly was the first dude to do sneaker culture shit in China. Brian and Edan and Johnny Tang are awesome. I'd recommend going there because I got to know and chill with those dudes. All are from North America and are down to skate and help you out. Avenue & Son is like a Helas offshoot I think, right? Cool product but didnt really spend time there.
Of course, there's so much shit in Shanghai. I stayed in the French Concession area which I imagine is less of a culture difference (i.e. breakfast sandwiches and shit like that) so it's cool to meet up at the center, skate flat, and then go to LP or explore. I have no idea what the name of anything was or how to get there except for the center and LP but yeah, have fun with it.
