Can Temporary Resident permit be renewed at any PSB?

I'm currently studying in China and the X type that I have is processed through the school..The question is:Can I go to another Province and get my study permit ? I'm asking this because the length of time(6mths) is very short for me to be renewing it and I heard that a longer time is given if I renew it in say,Shanghai for example .P.S it is an X1 type.
