Legal and education experts are calling for the Criminal Law to be revised to include the offense of child abuse after a number of incidents in which minors were physically or sexually abused have come to light.

In one notorious recent case, Yan Yanhong, an uncertified teacher at a privately owned kindergarten in East China's Zhejiang province, posted a photo online of her picking a boy up by his ears.

The child appeared to be shouting in the photo and seemed to be in great pain.
