Shenzhen: 9.12pm School's Out!

Another Monday night at the metro station: a swarm of high school students done for the day... at 9pm. Impressive considering the kids were in school at 7am. They'll be getting ready for The Big college entrance exam just around the corner, poor things.

And yes, the high school track-suit uniform is ubiquitous in China. At least you get to choose your shoes.
