Have you been to China? The tier 1 cities like Beijing and Shanghai are positively manicured compared to the average US city (or Paris, for that matter).
Of course it's a huge country and it's not too hard to find an open-air market with meat hanging on hooks or public lavatories that you wouldn't want to enter without a hazmat suit, but people emptying their night soil out the window into the street below is not really a thing anymore.
