Does the recent fog in Hefei have the same origin as that in Beijing and other cities in North China? In other words, is this one gigantic fog or many different fogs? If things continue like this, I think we'll all be too dead to enjoy Hefei's development in 10 years' time, and I would definitely not raise a young child in a city with such poor quality of air.
But now that we know the worst offenders, which are the best places in China to live for quaility of air. I imagine coastal cities. But does anyone know for sure?
