Hi Kai
Greeting from Peggy, Top China travel.
Till now, the transporting information I've checked is in the following:
1) Taking No.10 Line in Hongqiao Subway 1 Terminal Station (Hongqiao Station to Xinjiangwan City direction), after 14 stations, getting off on Tiantong Road Station
2) Changing to take No. 12 Line in Tiantong Road Station (Qufu Road Station to Jinhai Road Station direction), after 2 stations, getting off on Tilanqiao Station
3) And then, walking to the east for about 200m and you will get there.
Peggy
