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.

Dragon Boat Festival
发布者Thanks for this. I always wondered what could possibly connect the ferocious paddling with triangular snacks. And was obviously too lazy to look it up for myself.

发布者And on not wasting water: get rid of Taiyangneng. The amount of water you waste while waiting for it to warm up is simply silly.
Hiking from Daju to Lugu Lake, part 1
发布者I recently undertook a bike trip to 'Big Tool' and put some pictures up of the same valley. It's amazing how dreamy it is.

Later, I heard that Daju used to be quite busy but the requirement to pay 200 RMB per person to simply use the road next to Yulong reduced the influx of tourists to a trickle. There is still an establishment rocking a "Best restaurant in all of China" sign, it seems to be mostly used for playing Mahjong as was the hotel we were staying in. Surprising they weren't out of business yet.
The next day we crossed the Yangtze and mounted on the other side. This also yields interesting pictures of Daju.

Chinese academic ponders globe-spanning railways
发布者No country will be very happy to allow an increasingly militaristic China to build tracks that could one day roll an entire regiment to their doorstep. Not going to happen.
