the more you think of going back to China, the more likely you will. My rule of thumb on this issue is simple: no matter what you are here in Canada for, finish a degree first; if you do not see a career in front of you in North America after your degree, go back to China with a western earned degree (and make sure you work hard to improve your English during the course of your study). Do not stay here working as a labor worker or washing dishes in Chinatown because I think you have something else better to do in China.
