Hi, How do i go to Liuheng island from Pudong Intl airport?

Well, I cannot find the updated schedule of Nanpu Daqiao Bus Station to Dinghai Port.
But I can also provide an easy way for you: Airport Shuttle Bus + Coach + Taxi +Bus
From the airport, take shuttle bus line 7 to South Train Station. Then walk northeast to find South Bus Station. There are many coaches that can take you to Ningbo South Bus Station. Take it and then take a taxi to East Bus Station. The cab fare is about CNY 20. After that, take direct bus to Liuheng Island Taimen Passenger Terminal. :)
