That is, funny, but stereo-typical
Korean
They're perhaps the only ethnic that can spend all days playing games and maintain a 4.0 GPA at the same time. Mainly because they have some kind of drug in Korea that makes them about 12x smarter than an average person. They're generally really pretty and some girls have this hardcore Korean look (small eyes thin nose) which I dig. In-all, Koreans are all around really nice girls. :) However they have this thing where they can only date Koreans so that's a big hurdle.
Japanese
They can either be real hot or real ugly. There's a pack of them walking around SFU one day in those sailor-moon outfits and none of them caught my eye. I hear they're quite obedient and more dedicated but not sure if that's true nowadays but I also hear the Japanese guys aren't. I also heard they like to do all sorts of kinky + wild stuff so you may want to watch out for that. Things that might include excretion and beatings. Aside from that, the hot ones have this cute Japanese baby doll/innocent look that looks totally adorable, even more so than Koreans (but I'm still biased toward Koreans, can't do a damn thing about it).
Chinese (CBC/ABC)
Also known as Canadian Born Chinese/American Born Chinese. We're talking about girls that are raised in Canada (or America) and not necessarily born there. Like all the other Asians they got the brains. Since it's Chinese you would see a huge population that varies a lot. There's quite a lot of ultra hot ones here and there and there are some average ones. They're generally quite nice (personality-wise) but again you might get some bad ones. Since they're raised around here they are not that treacherous like HK'ers (in a relationship). They might not be totally traditionally Chinese but they (or some) won't stray too far from it. Overall, CBC/ABC's are pretty nice and they're OK'd by me!
Chinese (Hong Kong)
We're talking about girls that are raised in Hong Kong are not necessarily born in Hong Kong. Hell I was born in Hong Kong but I considered myself as a CBC. They said I'm "too slow la". Anyways. Here in North America, they're generally dumber than CBC/ABC's because their English sucks. Watch them piece their Chinglish together. The dumbness increases as the school grade increases (even into University). They wear so much make up that you can rip them off their face just like those masks from Mission Impossible II. However they're more updated than ABC/CBC's as in fashion and such, know how to dress, and know how to make themselves hot (sometimes even if they're not). They're materialistic and costs $$ to maintain (more $$$$$$ if they're rich). They're difficult to get and maintain. More importantly, they're very likely to be players and/or golddiggers...they switch their "signficant other" like every 3-6 months. Beware! I wouldn't want anyone from HK.
Chinese (Mainland)
I got a lot of emails telling me to split Mainland and Taiwanese so here am I taking more time to observe and bring this info to you. A very sad thing to do really. So anyways I looked closely and I did notice a difference. I'm surprised I haven't seen it before. First of all again I must mention that I still cannot stand the sound of Mandarin. I'm sorry but it sounds very annoying. I also notice that wear these puffy, funky-color (such as green, cyan, white, red, etc.), communist-styled jackets. If they're not in those standard issue jackets they look like as if they came straight out from China. For some reason they're not bothered by the pimples on their face (which is nothing wrong, just something I noticed). However, they're actually quite nice people (don't judge by the looks) and likes to help each other and very cooperative. They look like they're quite faithful in relationships unlike their HK cousins. :)
Chinese (Taiwanese)
There's actually quite a lot of similarity between Taiwanese and Honger girls. Taiwanese is by far the hottest looking from the Chinese group, even slightly more than Honger girls. They're actually very updated (like HK). I probably must have mistaken Taiwanese girls with Honger ones dozens of times. They do know how to dress and make themselves looks good. You won't see a lot of makeup on them which is good, somehow I find that they look good even without makeup (like Koreans!). However I hear their personality is somewhat bossy and demanding, but the ones that I worked with seems quite adaptable and pleasant to work with. But still I could not stand the high pitch whining of Mandarin. Guess that's something I can't live with. Relationship wise? I hear good and bad things about them so it's really hard to say. Go with your judgement.
Viet
Don't mess with them. Or their boyfriend would kill you. If they don't have a bf they will find one and kill you. They sure have a lot of connections. One thing I need to mention is that they have great figures.
Flip (sp?)
They are actually very nice people (personality-wise), probably the the nicest from this list. They like to help people, I can tell you that. Some of them looks pretty good too, like the one that works in Cactus Club down in Broadway. :) But the rest, kind of average.
i'm mad that the one for filipinos was so short!~! 
It is stereo-typical! 
What guy is this, Val?
