I hope anybody can answer my question.
I'm holding a student visa here in china and i'm going to renew my passport, my visa will expire in MAY, and I will get my new passport next month. My questions:
1. Do i have to transfer my visa to my new passport? I ask to my school about this, but, they just said, there's no need for me to transfer it, that it's OK if i don't transfer it. Do you think they are right??
2. If i don't transfer it, I won't be over staying in china, from the time i get my new passport to the time i renew my visa?

I hope somebody will enlighten my mind about this.
Thank you
