There is no direct transport connection from Pudong airport to Yangzhou. You can take airport bus Line 7 to Shanghai South Railway Station first and then there is only one train every day to Yangzhou, leaving at 10:44 and arrive 5 hours later. I recommend you go by bus which is faster and easier to get, although more expensive. Take airport bus Line 5 to Shanghai Railway Station. The bus station in the north square has several buses to Yangzhou. To get to the bus station faster, you can choose maglev train to Longyang Road from Pudong airport and then to SUbway Line 2 to People's Square then to Line 1 to Shanghai Train Station.

any idea what is the estimate cost of the bus to yangzhou then?

Hi Alan, the bus fare from Shanghai to Yangzhou is about 95RMB/adult.
