I'm from Singapore (I'm a Chinese too by the way), and I can draw in Manga style, write and speak Japanese, Mandarin and English. (Although my Japanese is still in a beginner's level...)
Being from another country does not mean that you can't pick up skills and cultures from another Country. Its not like People from the US or Europe can't learn Kung Foo, Japanese Flower Arrangement and other things like another language right? Sides, some people in my Taekwondo course (That's a korean Martial art) are PRC immigrants too.
Anyways, I have a question; How is the DiaoYu island issue coming up? I am both concerned for both sides and hope nothing drastic happens... I don't want to see both of my favourite countries fighting one another...
