A keeper of cleanliness at Forbidden City

Gao Caiping, 49, cleans the "four-star" toilet at Beijing's Forbidden City. The toilet has three Western-style pedestals and 11 squat units that she says she needs to clean "without a break".

A "four-star" toilet is one that's at least 100 square meters and has separate units for men and women, and provides free toilet paper.

She has worked there since last summer. And it isn't an easy job because the Forbidden City receives a little less than 10,000 domestic and foreign tourists from 8:30 am to 3 pm daily. The pressure goes up on weekends and holidays, when more than that number visit the historical Chinese landmark.
