It seems everything has somthing to do with Olympics now in China, and the most intimate are those sponsors. You can see the big characters of Olympic (in Chinese) and Coca cola at the backdrop.
My collegue took the photo at Yellow Dragon Sports Center on our way back to the station, (know more about the stadium, click its wiki link http://en.wikipedia.org/wiki/Yellow_Dragon_Stadium)
Chinese kids are too much familiar with this friend. When I was a teenager, I drank so much of it that my dad used to say "more than the water you've had".
Still wish you a happy Monday~
