Pollution is far better in some places as they crackdown on factories and such. There was one point in Shanghai where pollution just kinda... became way less overnight. Right now it's 57 which is England levels, It might go up to 150 odd sometimes but the overall average is like half or less of what it was 2 years ago.

If there's one thing China is actually doing right... and I can maybe count two things total... it's fighting pollution
