Over the past 11 years, she has used a toothbrush to clean cemetery sculptures, monuments

Every year during the run-up to Qingming Festival, a stooped, gray-haired woman can be found on a ladder cleaning monuments in the martyrs' cemetery at Yichang, Hubei province, with a toothbrush.

This has been Tsering Drolma's routine over the past 11 years. It usually takes about a month to clean all the sculptures.
