some Taxi drivers may come to you when you exit the airport, pretending that they speak english and that they know exactly how to take you to your destination, try to ask them something in English, you will be surprized, and ask them for a receipt, each cab has a printer attached to the meter, it should start printing and making noises as the driver pushes the meter`s scren to reset it, if he didnt reset the meter, nor activate the printer, prepare yourself to pay a very huge fare, I paid the first time I came 500Yuans, from the airport to my hotel near the city center.

ask at your hotel`s front desk, about the card indicating your hotel address in Chinese, and other useful addresses
this card usually contains also useful sentences like: take me please to:, or how much, or I need a receipt.
the divers are used to this card, just point at what you want and thats it.
