Vicious dad in China films himself smacking daughter, 5, repeatedly -- to win ex-wife back

Gifts, grovelling and admitting that you are wrong are just some common methods that people use to woo a partner back to them.

Not for this man in Daqing, Heilongjiang Province, however.

In a lousy attempt to win his estranged ex-wife back, the man named Jiang filmed a video that showed him repeatedly slapping and hitting his five-year-daughter while she was sleeping.

The girl's loud cries can be heard as he cruelly beats her.

Jiang claimed that he had hoped that his former spouse would see the clip and be so moved that she returned to him.

He was subsequently arrested and detained for 15 days, while his ex-wife took custody of their child.
