Last year, I was in Hefei, for RoboCup. 4.5 million inhabitants, yet I've never heard anything about that city for anything not related to our trip there. There was construction work going on everywhere, new apartment buildings going up, completely new airport, roads: busy everywhere. Unfortunately, I didn't see the sun for a week because I was either inside, programming for RoboCup and the times I was outside, the smog limited visibility. I have no idea what the skyline of the city looked like or get and idea of how big the city really was because I simply couldn't see further than 500m.
