When you look at that graph, and, indeed, today's, you'll notice that the peak moments coincide with low wind speeds. Winds are very strong in spring afternoons and I believe they blow a lot of the pollution away. When the wind dies down at night, the air fills up with pollution again. From diesel trucks, certainly, but construction, too. And agricultural stalk burning.
What puzzles me is that the humidity, which reaches 100% at night, doesn't precipitate the pollution. I thought it should?
Anyway, high AQI rates are common for Kunming in spring. But that doesn't mean it isn't utterly disgusting. We should all be aware that we're slowly being killed here.
Getting Away: Sapa
发布者Can we not mix up "hiking" and "trekking" please? Backpacker speak makes me sick.
Trekking > to travel or migrate, especially slowly or with difficulty
Hiking > to walk or march a great distance, especially through rural areas, for pleasure, exercise, military training, or the like.

City cracks down on illegal vendors
发布者They are sure taking away a lot of the charm of living in Chinese cities. Are all night-time noodle stands illegal? What do those people normally make their living off? Yet I agree that the street vending has become a bit mad and if they want traffic to one day flow smoothly in this city, then these things must be taken off the streets.
I hope the chengguan this time kept their manners.
