Every child should be taught good manners – wipe your feet before entering the house, say thank you when given a biscuit, finish your parsnips and refrain from telling Grandma she smells like the attic.

Now in China, in the village of Huangping, the notion of politeness has been extended a notch, and kids must salute passing cars.

The road to school could end up scattered with fuming cars, broken poles and injured people. Kids could be in great danger.
