Hello, does anyone know if there is a bus connection between Shanghai city (preferably Pudong airport) and Lishui city in Zheijang province?

I'm afraid there is no direct bus operating between PVG and Lishui. It is suggested to take shuttle bus line 5 to local main railway station, walk from which to the nearby General Bus Station. There you can take a direct bus to Lishui. Buses for the journey are scheduled at 09:10, 12:25 and 16:30.
