Hello, Bobby. As my answer above, you can take maglev train to Longyang Road then change to Subway Line 2 to Nanjing Road (get off at: Nanjing East Road, People's Square or Nanjing West Road), it costs about 50RMB. Do not suggest go by taxi. Or you can take airport bus (Line 3 or 6) to Longyang Road and then change to Subway Line 2, which costs much cheaper, About 20RMB including subway anf bus.
