Twin sisters have been tied up for every day for the past 10 years by their father.
Li Wancheng has bound his 12-year-old daughters' hands each day because he says they would harm themselves if he didn't.
The family lives on a roadside in southwest China's Yunnan Province as Li tries to save enough money to get treatment for his daughters, Li Luqin and Li Shuangqin.
Wancheng said: "We only have 1000 Yuan (£100) of savings. We don't have extra".
On the roadside, passers-by reacted angrily to seeing 12-year-old Luqin tied with one hand to a steel fence and another to a tree.
While bound Luqin cried and struggled, trying to get free from the rope biting into her wrists, her father said: "When they were two they were found to be not normal. The elder Luqin would hit herself from time to time, and her sister Shuangqin can't walk.
"The local hospitals couldn't find the reasons but gave the diagnosis that Luqin is mentally disabled while Shuangqin is physically disabled."
Today, he says Luqin doesn't recognize him, while Shuangqin is unable to walk unaided.
Sympathetic onlookers requested the father release Luqin from the ropes but once released she hit herself on the face with her fists.
Li Wancheng then had to struggle to tie her up once again.
