I belong to nowhere

I have been in New Zealand for almost 11 years now since 2007, and I am now 23 years old, so mathematically I am half Taiwanese, half New Zealander. I am affected equally by both cultures. People always said those people who have been to overseas are better than those who haven't because they are capable of looking at things from wider perspectives. However, for some reasons, that's not really happening to me. My English is barely ok, even though I have been here for 11 years, as I wasted too much time with asian people in my college years.

And I can no longer be proud of my chinese anymore, I can read and write, but I can't really express myself nicely in chinese anymore.

I feel like i don't belong to anywhere, I don't have a home. Where will my soul go when I die? New Zealand or Taiwan, or somewhere else
