Wow
Last 4 guys are probably under complete control by some overbearing b*****. Sad. Not the "b" part, but the submission.
As a single man, have fun mate. Smile, be friendly - you'll have the time of your life (assuming attraction to Asian women). There are Western women, just not as much - but enough, if that's what your after. Tung Chung - yes, but you'll have to socialize 'in public' - mall, restaurant, etc. Best times I've found, meeting girls that way (just like home). Wanchai, LKF, Hollywood Rd, all good with plenty of bars. You really have to be anti social to strike out here. But yeah, Tung Chung won't have the 'bar scene'. There are some minor places here and there for night clubs, but you'll really need to travel to central.
Don't feel threatened by the girls looking for money. Almost always cheaper and less stressful than my girlfriend, and more so than my wife!
