I just wanted to post that today is such a beautiful day in southern China. After a short winter, but tough since no apartments here have heat, today was so nice. Clear, good air quality, and about 78*. Oh, these times make me love it here.
Well, I'm in Guangzhou which is huge, and many factories. The air quality gets pretty bad in the summer. However, this year they have banned the use of all motorcycles in this city (and there were houndreds of thousands before) so the prediction is air quality should be better this year. (so far it seams so) On bad days though, it is very, very noticeable as far as seeing, and breathing.
