Nude photos of over 20 boys posted online by their kindergarten teacher have met with an outpouring of protest and anger from parents and netizens.

The boys of Canjiadian Kingdegarten in Luoyang, Henan province were told by their teacher Ma Wenli to take off their clothes and pose in front of the camera. She then uploaded the pictures onto social media.

Ma said she had good intentions, explaining that she had posted the images online because she thought the boys were cute. The photos were taken as a way of sexual education and teaching about life, she added.

Parents have accused Ma of being insane. Besides, the local education department stepped in, asking the teacher to leave her position and apologize for what she did.
