How do I get the ticket and into the bus to Suzhou at Pudong Airport?

The buses are frequently scheduled, so generally people buy the ticket on the spot. the ticket office for the bus can be found at Gate 6-7, 8-9, Arrival Hall, Terminal 1 (T1); exit of bus parking area, P1 (in the airport long-distance bus station). With the ticket, you can just go to catch the bus.
