HI5! I was born in China, I've been in the UK altogether for 10 years? I think I have a fairly neutral british accent, or try to have one anyway. My friends say they can't tell if I was born here or not. I have a fair few chinese friends, more than half I think, not by choice, but because of similar interests. I don't discriminate when it comes to who I talk to, and who my friends are. Sadly, my parents do, and want me to have more white friends, which is near impossible considering she imposes a 9PM curfew (and still does even though I'm 18!!!), not allowed to go clubs, go to parties, invite people over etc etc
And how can THEY call you wannabes and try-hards? It's only right that you integrate yourself in the culture that is around you (assuming you are not in Malaysia, but somewhere else), and learn to speak their language. I find it ignorant when people (not just chinese) who go to other countries eg spain, and expect the same language to be spoken, same culture as if they're at home! Totally defeats the purpose of going abroad does it not?
And being chinese and all that, I bet you can integrate better than them anyway regardless whether it's in the realm of calculus or not
On a slight side note, when I went back to china for a year for family reasons, and went back to the school that I went to before coming to the UK, I was sometimes called fake-westerner (or fake western devil literally in chinese) because I can speak fluent english. Most of the time lucklily, it was jealous people saying it as a joke. But sometimes it isn't, and is really piss taking...
