Stock up some ￡¤10 bills in case of the vendors and taxi drivers cannot make change for big note.
Counterfeit bills are a problem in China. Very few Chinese will accept a ￡¤50 or ￡¤100 bill without first checking to see whether or not it is a fake. Notes that are old and tattered are also sometimes hard to spend. If you are having problems with a note, exchange it for a new one or small change at the Bank of China -counterfeits, however, will be confiscated
