how to go to mt putuo via shanghai overnight ferry

The tickets can be bought at No. 59, East Jinling Road and the place to board the ship is at Wusong Passengers Terminal at No251, Songbao Road.
Since I do not know where you are, so I can just tell you the direction in general.
To reach the ticket office, you can use the local subway line 10 to reach Yuyuan Station and then take a taxi to reach the ticket office.
To reach the port, you can use the local subway line 3 to reach Shuican Road and then take a taxi to reach the port.

Thank you! If i will comong from the office in Yuyuan where i will buy tickets, how will i get to Wusong Port?

Shuican Road

Where do you alight from line 3to get to Shuican Road in Shanghai? There re 5of us can we ride in 1cab?

From the ticket office, you can walk to Yuyuan Station where you can take line 10 to reach Siping Road. Then you can change to line 8 to reach Hongkou Football Field and then change to line 3 to reach Shuican Road.
5 people cannot be taken in one cab in this city.
If you have 5 people, you can take the line 3 to reach Songbin Road Station and then walk to reach the port in about 20 to 30 minutes.
