You must notice Buffalo about your address change. If you stay in China more than 6 month, you will also be asked to submit a new no crime certification that covers that period. Otherwise your case will be either delay or denied, as metioned in CIC website.

Any "smart" thought may cause you big trouble. 5 to 8 years waiting is common in China, but you still have chance. If you try to do some "smart" way, probably you will totally lose your chance. the only smartest way is following exactly what are told to do.
