These photos are not so much for the images of the buildings, but for the sky. Do not be fooled by the grey sky into thinking that those are signs of a cold and cloudy day. It was a hot summer day, and that is the smog. I had never experienced air pollution until I came to Zhengzhou. Some days are so bad that I can barely see the high rise buildings on the other side of the CBD where I live.
