Beijing International Airport is northeast of the city and the campus is northwest. When you arrive, you need to exchange some money immediately, and you can do that after you pass through immigration and pick up your bags, but before you go through customs. Bring some US cash. ($100 = approximately RMB 775 yuan) There are also ATMs in the terminal after you pass through customs which are generally reliable. DO NOT ACCEPT OFFERS OF HELP OR A RIDE FROM ANYONE IN THE TERMINAL. Just tell them you are not interested. Proceed to the outside of the lower level to the taxi queue at the right side of the second lane. You line up for a taxi and the attendant will put you in the taxi and give you a card with the taxi number on it. It's good to keep that as a record. All taxis have meters and the driver will start the meter. In addition to the fare, you will have to pay 10 yuan for the Airport Expressway toll which will be added to your bill. The entire taxi bill should be 100 yuan or less.There is no tipping expected in China either in restaurants or taxis. (If you add a tip to a credit card receipt in a restaurant, it goes to the management.)
