Good news, Shanghai subway line #4,#6,#8,#9 opens.
Dec 29th is a big day for Shanghai. there are 4 lines open.
My office is located nearby LuBan station of line #4, so subway can be one choice to go to work.
Line #4 has outer circle and inner circle, which is around the Shanghai, including PuDong and PuXi. And the interval is about 13 min. If you plan to go by line #4, the thing you do first is noticing the time table, or if you are in emergency, it is not a good choice. But if you know the extract time, you can go by it.
