The lack of sex education, especially concerning how to prevent abuse of young children, is in the spotlight following the release of a code of conduct at a primary school in Yangzhou, Jiangsu province.

The code, which has been distributed to students at Meiling Primary School, tells pupils that "body parts under shorts and underwear should never be touched by other people", and that "you should tell bad people's secrets to teachers" and "you can lie to bad people".

Ma Jifen, a sixth-grade teacher at the school, defended the new code.
