if you have social insurance card, and medical insurance card, you can get your tempary drive licence there( test centre), after your pass knowledge test. then you can get your normal drive licence after your pass road test.
if you have drive licence in china, you can drive here in 6 months after your licence is proved.
Don't call them just go there, I know most of them dont know much of it.
that is my experince, hope it will help u.
