Go Expat - it's probably the ultimate way short of travelling in and around Asia
Working in HK and living in HK can be pretty hard if you are used to big spaces, but if you're adaptable, outgoing and pretty confident, there's no risk at all! Everyone pretty much goes out all the time and if you just go out with the frame of mind of meeting people, you meet a hell of a lot of people!
I'd agree with the comments above though. I'm ABC, pretty aussie so I have a western attitude which the girls kind of love, that mix of good and good ;) - I do find some asian women become to passive in relationships which is not what I want. So the culture on culture thing can work for or against you. If she's wanting to be more western, but you like being asian, it could be rough
There are however ALOT of Expats in HK, so chances are you'd be mixing with ABC's from somewhere!
While you do meet a lot of people, and if you have a reasonable status, the thing I get annoyed with is trying to work out who your real friends are, or is it just networking.
There's a lot of give and take. Ultimately if you're not confident, I'd say you could end up in HK staying at home all the time. The real benefit then would be the punting which is so easy, you'd better be discipline.
Personally, i loved it and it's probably the one reason why I was single for so long
I have lot of friends who moved to HK though, and a quite a few relos!
