Ninety-seven-year-old Zhang feeds her paralyzed son in their simple home in Bozhou, Anhui province, on August 14, 2011. Zhang has five daughters and two sons. Approximately 40 years ago, Zhang’s youngest son, then 20, became mentally ill and was finally confined to bed 19 years ago, when Zhang started to take care of him all by herself. Although life is hard, when people come to offer her some money, she always smiles, saying “All good people are blessed”. [Photo/CFP]
