Many tourists hiking the mountain trail shared on social media their surprise at signs reading “purchase clean air to purchase a healthy life” and “Unpolluted air – big bags for 30 renminbi (£3) and small bags for 10 renminbi (£1).” The villagers made quick bucks as tourists bought bags of the stuff, they even put flowers in the bags to make the air smell even better.
Some internet users have suggested the villagers will make even more money if they exported the air to the cities.
