"The case is known as the Liu Xiaopeng case," Liu Xiaopeng had taken two wives, and together they had seven children.
He lived with his wives and children on the very edge of the mountain village and never allowed them to go out, keeping them imprisoned and abused for a long time.
Liu Xiaopeng was a proponent of polygamy, and even considered his four daughters as wives. His children were brainwashed over a long period to believe that their purpose in life was to serve their father, to become his slaves.
Later, one of the wives couldn't take it any longer and finally ran away. She brought the police to their home, exposing all of Liu Xiaopeng's crimes, and thereby rescued the children.
According to Liu Xiaopeng's confession, both wives had always wanted to escape, so he killed one of them.
He thought this would frighten the other wife into not attempting to escape, but she still found a way out."
