Miaomiao sweeps the road to her home, in an isolated village in Yichang city, Central China's Hubei province, Feb 23. Parentless, the first-grader has taken up a lot of resposibility in the family. Her grandmother, who is approaching her 60s, is mentally disabled, handicapped in the right arm, and is frail. Her grandfather suffered severe cracked skin disease, which makes him unable to be exposed to water especially in the winter. [Photo / CFP]
