Right now, Shanghai is experiencing the worst air pollution on record.  The Air Quality Index Scale goes from 0-500 (500 being hazardous).  Shanghai is at 509. 

I just wanted to let everyone know that Beijing is not experiencing this kind of air pollution at the moment. 

If you want to see up-to-date data on China’s air pollution, the following is a pretty helpful website.  http://aqicn.org/map/china/

Happy breathing everyone!
