The bemused referee blew the whistle to stop the match and other players could be heard asking the two to leave the pitch, but the furious woman marched straight towards her boyfriend.
And the embarrassed man appeared to know she was coming, trying in vain to avoid her by walking away.
In footage of the attack, she immediately begins slapping him and pulling at his top, shouting: "You're married and still fooling around?!"
The guilty man does not respond as she follows him around the pitch, slapping him on the face and repeatedly hitting his head.
She continues to shout at the man, who apparently hid the fact that he was married, turning his unwitting girlfriend into a mistress and secret lover.
She says: "I'm asking you a question! Are you married?"
She adds: "Your wife may not care, but I care! Are you married or not? Why are you doing this to me? Do I look like I'm easy to bully?"
Towards the end of the clip, the man turns his back on his apparent girlfriend and ducks in the corner of the fence.
Some of his teammates appear to try convince the woman to stop the punishment, but she drives them away with stares.
It is still unclear how the woman found out her boyfriend was married and how exactly the incident ended.
The footage is believed to have been filmed in Chongqing, in south west China.
