Chinese visa for a Brazilian living in Japan.

Hello there,

I'm a Brazilian citizen and received I job offer to work in Qingdao, before I accept this offer I would like to go to Qingdao and discuss this job offer with my potential employer. I've been living in Japan for one year on a Spouse of a Japanese national visa. Given that, what type should I apply to stay for over 3 days in China? Also what documents do I need to support my application and where should I submit my application?
