HELP: how finding a job in Shenzhen/Guangdong?

Hello everyone.
My name is Dimitri Van de Perre and I'm Master of Science (Biology) with + 4 years experience (Lab/University/Chemistry) from Belgium.

I've already visited Hong Kong and Shenzhen 7 times and I would like the opportunity to work in a multicultural environment and learn more about Asian culture and language.  I see myself as a real team player who loves a challenge. I would like to find a job near Shenzhen or Hong Kong.

I would like some advise of how to find a job in Guangzhou/near Shenzhen (my gf lives there and she wants me to come and live closer to her). I saw that all teaching possitions are only for native English speaker so i was maybe looking for a non teaching job (but i also have experience as teacher).

thx
