Two kindergarten teachers surnamed Zhou and Guo were detained for 14 and 12 days, respectively, and later fired for beating some 2 to 3-year-old kids in their class in Ruian, China's eastern Zhejiang province.

This incident went viral online when someone posted a news item on the Internet Thursday. Accurate and sufficient evidence was obtained before the administrative penalty was handed down to the two. It was reported that earlier, parents had found scars on their children's bodies, so they hid digital voice recorders in their schoolbags to collect audio evidence of corporal punishment.

After the beatings were exposed, the Ruian City Board of Education established a working group that cooperated with local police to launch an investigation. Sufficient evidence was obtained to carry out the administrative penalty.

All tuition, fees and other relevant charges have been refunded to the parents of the children involved and psychological experts have been engaged to carry out psychological intervention to the youngsters to ensure their mental health, the authority said.

The two teachers involved have been dismissed, according to Xinhua News Agency.
