Worker takes pride in upkeep

Che Xueqiao is in charge of six public toilets in Beijing's Fengtai district, making sure people's visits are free of unpleasant smells and other discomforts. Two of the toilets were built last year, while the rest were converted from traditional dry toilets - basically open pits.

"Inspectors check the toilets every day, so I work hard to keep them clean," said Che.

Che's job is part of the so-called toilet revolution. In 2015, a three-year national campaign to increase the number and improve the sanitation of toilets at tourist sites began. The campaign expanded to improve public toilets in cities and build better private toilets in rural areas.
