Shanghai Subways

The subway system is very modern and clean, though unfortunately very limited in its coverage - in a city the size of Tokyo (which has 25+ subways), Shanghai has three operating lines and planes for 6 or so more; not nearly enough.

Subway etiquette is interesting, and very unlike Japan. In Tokyo, as the car stops you move to the side of the door so everyone can exit; there are even little feet painted on the platform so you know where to stand. Once everyone is out, you enter the car.

In Shanghai, as the car stops, you stand right in front of the door and as soon as it opens, you push inside the car, all as people are fighting their way out. This despite the signs asking you to wait - during rush hour there are platform guys to help keep people out of the way as passengers exit, otherwise it would be very challenging. But otherwise the subways are very pleasant and convenient.
