I come from Wuhan, but I think the pollution situation in Wuhan has improved obviously in recent years. I haven't seen the blue sky for a day in the past year, and it's much better now. The most serious pollution in Wuhan was in the late 1990s.

If you have to find it, go to the river and shoot it. The Yangtze River used to be green in winter, but now it is always yellow.
