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.
Zen and the Chinese art of motorcycle driving
Posted byI intentionally crashed my e-bike into the side of a car that pulled up without looking onto the bike lane. Then I showered him with expletives. Also slapped the hood of a few cars on Xuefu lu that were in the bike lane and trying to get past the little bus stop. It may not help but it feels so sweet.
Some day I want to be brave enough like that foreigner in Beijing who just stopped his bike in front of a car in the bike lane and forced the driver to reverse out.

Posted bySlamming your hand on the hood is an effective method to deal with pricks in expensive cars. It makes them so furious but there's no way they can catch you as you slip away like an eel among the shoal of two-wheelers.

Posted byNo there isn't. You'd have to cross the border by yourself and then you can get a bus to Sapa. There are many options from official buses to mianbaoche equivalents. The ride is about 30 km up a hill so I'm guessing anything between 30 min and 1 hr to get to Sa Pa.
