5. School Closed on Account of Smog
If you live in an area that gets cold weather you used to have snow days, tropical climates may have had hurricane days, but in China there are smog days. There have been days where the smog over some cities in China have been so bad that schools were closed and airports shut down. It is already common practice to wear masks to try and limit how much of the smog is breathed but it is little help.
6. Say Cheese!
Did we mention how bad the smog is in China? So bad that in order for tourists to get a photo of the skyline in Hong Kong a fake backdrop had to be set up. Without the screen behind them it would just little like they were standing in front of a large grey cloud. This is one time when Photoshop is actually better than the real thing.
