I live in Nanjing yeah, but I'm laowai, I've only been in China for a few months. I only really know about the nightclub scene really locally, and from what I have read on the net. I hear Beijing is like the DJ capital of China, but its mostly hiphop, turntablism, and house/techno. Chengdu is supposed to be pretty good for dnb and breakbeat, seen some flyers for some quite big parties, and Shanghai is good because of the amount of young laowai that live there, the demand for more varied music in clubs is greater. Nanjing pretty much sucks for nightlife, I'd like to go to the above three cities. If you are interested, I can email you a demo of a mix and maybe some of my own tunes when they are finished, I'd love to come to Beijing to play, and if you're looking to import some DJs when the parties get bigger, I'm sure I can persuade some of the heads from this forum to come, I know Sayber is up for it.
