Many of my friends come to guangzhou,when they exchange money in the airport area,they get too much fake money, i have asked them where are they get the RMB, some of them say the exchange store, some of them say the taxi driver...

So the best way is ,before you arrive china, you can do some exchange in your country ,to make sure you get the real RMB. if you still need to exchange money, you can go to the bank here, it is more safely to get the real Chinese money--RMB
