The rash of violence has prompted public calls for more measures to protect the young in a country where many couples only have one child.

There was a particular string of knife attacks against schoolchildren across the country in early 2010 that killed nearly 20 and wounded more than 50.

In one incident that year, a man slashed 28 children, two teachers and a security guard in a kindergarten in eastern China.
