There has been an heartbreaking footage showing a deaf mute man sitting in chains after his own mother locked him inside a stone hut for more than 10 years.
Wang Zhiqiang, now 41, was born unable to hear or speak, his mum Yue Rong, 77, revealed.
But as a child he still showed signs of intellect, so his family sent him to a special needs boarding school.
Only his time there proved to be a traumatic experience after he was severely bullied .
As a result Wang Zhiqiang, who lives in Xuanhua in Dengfeng City in Henan, China, developed psychological issues.
And as his poverty-stricken family could not afford to seek help and treatment Zhiqiang’s mental disorders got worse.
His mother said: “He wasn’t able to go to school any more, and his condition worsened while staying at home.
“It reached a point where he was attacking other villagers.”
Yue explained when her husband passed away she found it difficult to cope which is why she resorted to chaining up her son.
