Xi'an, home to the famed Terracotta Warriors, has launched a citywide campaign to clean up its public toilets for a more pleasant experience for locals and tourists.

The capital of Shaanxi province has set up a leading group to steer the work and appointed "toilet chiefs", neighborhood office employees tasked with regularly checking facilities, according to the city tourism administration.

If a restroom at a tourism spot or attraction does not make the grade, the officials responsible for sanitation, including those at district level, will fail their annual work assessment, said Zhang Yongke, director of the administration.
