The past month has been rough, really. Even with plenty of sunshine, exercise has been undesirable.
A local chengduren told me that it’s because it’s wintertime which means low winds to blow that crap away, people who have cars are driving more (even short distances that in other seasons they might walk), farmers/peasants are burning more fires for warmth. Who knows if any of these are legit, but it’s interesting to think about.
A total guess on my end is that with Chunjie coming up, factories are working harder to get production up before the break.
It’s been really dry too, I feel like a good rain would wash some of it away (and onto our dongxi, but oh well).
