The video, which surfaced in January last year, showed the woman in an apparently confused state in the eastern province of Jiangsu.

It was seen by millions, stirring debate about the treatment of women and in particular the trafficking of brides in rural areas.

A man called Dong Zhimin had bought the woman for 5,000 yuan and had kept her chained up in a room without sun, electricity, and running water since 2017, the Jiangsu Xuzhou intermediate people’s court said in a statement today.

Dong was jailed for nine years yesterday for abuse and illegal imprisonment, the court said.

The woman, who suffered from schizophrenia, had been sold twice before ending up with Dong.

She had eight children during her time with Dong from 1999 to 2020, the court said.

Another five people who bought and sold her were jailed for eight to 11 years for trafficking women, the court said.
