i've had a few friends get jobs from this site.  but like all sites, this place is plagued by recruiters as well.  also, if it is a part time gig, make sure you do it legally.  you still aren't legally allowed to work under a student visa.  i know there are those loop holes where the school you study at can give you some letter saying blah blah blah but still... be careful and good luck!

Send you Resume daily to the job adverts, you're interested. Don't worry for replies. Chinese won't reply, if they aren't truly interested.

I prefer to visit part-time jobs in person. Door to door.

I would recommend Nanjing New Oriental (IDF). Visit their main office (don't know the address), and you'll be able to land part-time job, or leave your contact address with the manager. They also have different language courses, so your French might be interesting to them.

Good luck!
