I am holding an Indian Passport issued in India and have the Chinese Visa in this passport.

I am holding an Indian Passport issued in India and have the Chinese Visa in this passport. My stamping pages have gotten over. Can i apply for a re-issue of my passport in China ? As I understand, on re-issuing of a passport, the old one is cancelled. But if it is cancelled then how will my Visa be valid? Please clarify
