One of the two airports in Shanghai, the main one has two terminals, flights to Europe and America depart from terminal 2.
It is very well signposted, very easy to find the airlines. They have a lot of lockers in case they have time to go on the Maglev to Shanghai, in 10 minutes they will be in the city.
If they arrive, change money at any exchange office at the airport, there is not much difference and the taxis have approximate rates depending on where they go.
