People definitely have their hang out spots, so I'm not really referring to where they live. As mentioned above thanks bros, the hot bitches trophy wives tend to go to Central to shop. Young local girls tend to hang out in MK and causeway bay. I mean, you know the dress up like Japanese look? heavy makeup with dyed and permed hair, you tend to see more of those in MK than anywhere else.
Keep your eyes open, you'll notice the difference soon enough.
As for local universities I think it'd be hard to compare. Most people haven't been into one not to say all of them.
