Take Line 2 to Hongqiao Railway Station. How can I pick someone up? It's best to leave the station and check the tickets. . . .

You can make an agreement with your girlfriend to let her choose one at the north-south exit, otherwise there will be no one at all. Then you go to Hongqiao Station early that day, arrive at the floor of B 1 (the floor where the subway comes out), and find the south exit or the north exit. Take a closer look at how many platforms D542 1 stop, and then wait there.

In addition: there are several train exit doors. Don't let your girlfriend go away. Tell her to get off the platform and look for the nearest exit door.
