For me, it is business opportunity and adventure.

To be abused and shouted down by other expats on internet forums.

For me - love (met my girlfriend here while visiting last time), learning the language (always wanted to do), experiencing and learning about a place that is SOO different from the west yet just as relevant and to post long boring diatribes on expat internet forums :-p

I'm a social anthropologist, and it is easier to study my subjects if I'm in closer proximity to them.

Also, my fiancé lives in kunming.

cheap living price than Western.interesting culture,business potential, sexy girls,smart guys,bla bla bla~~
