A teacher has been caught on video slapping four young children more than 120 times when they failed to answer questions.
One father said his daughter was slapped his daughter 43 times and kicked her twice within half an hour.
The disturbing 30-minute CCTV footage was recorded at a pre-school in Taiyuan, in the northern Shanxi Province.
The incident came to light after the father, only named as Mr Han, came home to find his daughter's face red and swollen.
He visited his daughter's playschool and demanded to see the CCTV tapes, which revealed the teacher abusing his daughter and three other children.
"She should not be a teacher," Mr Han said. "She is a monster!"
The dad said this was not the first time his daughter had returned from school with bruises on her face, but he had always assumed she had been injured while playing.
He added: "The teacher asked my daughter to add numbers more than 10. My daughter told her that she can't solve it, and then the teacher slapped her."
According to a Chinese news report, the teacher in question has been sacked from the pre-school.
