I’m an American in Hong Kong. Based on what I know, your novelty and status as a foreigner (I’m assuming from your English you’re a Westerner) will be a bigger factor than the music you play. When I’ve been in the Mainland, (Shenzhen/Guangzhou) I got stared at quite a bit, and I was just walking around, not DJing.
My guess is that they will lump everything you play into “western” music. So this could be both good and bad, because you could get an incredible amount of freedom to play whatever you want. But they may be only familiar with the big western hits and you may be stuck playing those. Or your audience may react to your music as a novelty act.
However, I have to be honest: I have not actually DJ’ed in Hong Kong yet. Maybe somebody else would have better info. Hong Kong seems like New York in that people will dance all night and only stop at 10 am the next day. From what I hear, Shanghai/Beijing are like this too. I’ve heard grumblings from local DJs that club owners and audiences only like Western DJs, with clubs emptying out as soon a local DJ steps on the decks.
How all this plays out in Tier II cities is unclear. But my mainland visits convinced me the Chinese love to dance. People were even doing the cha cha in the streets! Personally I think it’d be a lot of fun to DJ in a Tier II city. People are ready to let loose.
