Can you enlighten me how do I travel from Hangzhou (Wushan Square) to Putuo?

From Wushan Square, you can take subway line 1 to get to Passenger Transport Center Station, Exit D. Then walk northwest around 450 yards to get to the coach station. There are several buses that can take you to Putuo. The schedules are 07:00 to 18:45. After arriving, take the ferry to the mountain area. :)
