A few weeks ago, Harbin, China was so beset with horrific thick choking smog and fog that drivers couldn't see where they were going with their headlights on in the middle of the day. This was a combination of weather patterns, coal burning to fuel a city-lentral heating system, and some weather patterns bringing smoke up from the south.
Anyway, it's nice to see that the clouds have cleared in time for the winter festival. These are some AMAZING snow sculptures. I'm glad they're visible.
