Subway is always my favorite transportation. To me , it is more than just a convenient way to go around, it is also a way you can feel the heart-beat of a city. In Shanghai, it jumps in perfect.

It is like a romance between a small, beautiful ballad dancer a giant, iron cold wrestler.  Late night, when everything dies down, the trains are still running but picking up fewer and fewer people.
