A man slapped his best friend's wife who took part in a kissing competition with another man in southwestern China.

The video filmed in the city of Zunyi in Guizhou Province on November 10, shows a man running onto a stage where couples were competing in a kissing competition.

He then stopped in front of a woman and slapped her several times.

According to local reports, the man is the woman's boss and he is also the best friend of the woman's husband.

Since the woman wanted to win the prize, she went to the event with a stranger although her husband and her boss did not allow that.

The man has apologised to the public, reports said.

11月10日，贵州遵义，一场接吻比赛活动中，台下一男子突然冲上台，对参与活动的一名女士脸部、头部有击打推搡等动作，工作人员见状迅速将打人者带离现场，后续活动继续举行并顺利结束。
原来，该活动只限情侣或夫妻参加，打人的黑衣男子是被打女子的老板，也是她丈夫的朋友。女子为了获得奖品，不听丈夫和老板的劝阻，执意带了另一个陌生人参加了比赛，最终导致了该起事件的发生。目前，该事件已经达成了和解，警方也没有追究打人男子的相关责任。
