When i went last year, i started with a 60-day visa, but then i went to a government office there and did an application for a residence permit because i was studying until the end of the year. i had to get a thing signed by my teacher at the school saying that i was registered there. Once everything got stamped and approved, then my 60-day visa was canceled and i got a residence permit that expired at the end of my study term (almost a year). I also had permission for multiple entries, so i could fly back to canada for vacation and then come back to china without starting over again...
