Zhao Na, 26, lives in Changchun, northeast China's Jilin Province. She suffered from cerebral palsy in her childhood. Her parents divorced when she was five. 15 years later, her mother got blind and paralyzed due to illness. Since then, Zhao has shouldered the family burden. Zhao can only control her feet, so she does all the housework with feet, from making meals, feeding her mother, to washing feet for her mother.
