Teenagers in Hong Kong have been told to play badminton to curb their sexual urges.
Guidance published by Hong Kong's education authorities advises teenage boys and girls to "master their sexual desires" to promote "correct" societal values and the 70-page document handed to children aged between 12 and 14 tells a boy and girl studying as a pair to "go out and play badminton together in a sports hall" should they become aroused.
Another example states that a young couple who spot others partaking in intimate behaviour should "leave the scene immediately" and enjoy "the sight of flowers and trees in a park".
The document has been condemned as "out of touch" and "regressive" by critics but Hong Kong authorities have defended its publication.
Education Secretary Christine Choi Yuk-lin said: "We should teach them to take responsibility for themselves correctly, to understand how to take care of themselves and respect others.
"When they grow up, they will face a more complex society and environment.
"Our approach is not conservative - we wish to protect the young people and equip them with the right values to face adulthood and the complexity of society... and it's illegal to have sex with an underaged person."
