A couple have locked up their daughter at home for 10 years.
Qu Zeli, now 17, had become retarded because of her treatment, the Beijing Youth Daily said.
Zeli was seven when she was last allowed by her parents to leave the house in Chongqing, Sichuan province. Then, she was a normal, intelligent child.
But following her imprisonment, the girl 'still has the mind of a young child', the paper said.
Zeli remains inside the house, behind windows covered with heavy steel bars.
The girl frequently threw things out of the windows and called out to passers-by. Occasionally, other children took her things to eat, the newspaper said.
Neighbours eventually reported the situation to the head of the factory where Zeli's parents worked. But the boss did not have the authority to make them send her to school.
