What bus do I take to go back to Shanghai from Zhouzhuang? And what is the schedule of the bus?

As I know, direct buses are available at ZZ Bus Station to Shanghai. It may take around 1.5h to arrive and the schedules are 06:30, 09:15, 10:20, 11:20, 13:20, 14:20, 15:20 and 16:30. This is just for your reference and it is best to recheck the schedules on the spot.

Have fun!
