In a shabby public bathhouse down a small alleyway in Changchun - the capital of Jilin province in China's northeastern rustbelt - a stout woman scrubs the toilets and gives female customers back rubs through the course of the day for five yuan a rub.
Her service is popular and she can give up to 25 back rubs a day. The women tell her they like her strong hands kneading into their shoulders, but the 34-year-old is too embarrassed to tell them how she came to be so powerful. Zuo Chunlan was a top weightlifter who won the national championships and even broke a world record. But now, after years of devotion to her country and her sport, she's in poor health and destitute.
