How can I get from Shanghai Station to Nan Xinyuan Hotel in Hongkou District?

Are you walking from the train station? Go there and ask the conductor where is the best line 3? Because it’s not easy to tell. Very close. South Exit 3 of Shanghai Railway Station is Metro Line 3.

Then after you enter the Line 3 station, take the bus towards Hongkou Football Stadium. Get off after 3 stops. This is a screenshot after arriving

Look carefully? After getting off the bus, you need to exit from Exit 1. You'll find it by walking east along the park.
