Yes, the province of Heilongjiang, the most northerly part of China, has passed a law requiring parents to prevent their children from falling in love. They post some comments in reaction to the new law too.

Student's parent, Ms Zhang: It will guarantee children's healthy development.
My child will be 15 years old this year, and I'm quite worried that "young love" will affect his school achievements... Making a law to prevent young love will guarantee children's healthy development, and is a demonstration of love to minors.

Netizen Mo Jinjin: It is completely unnecessary to make a law to prevent young love.
"Even an upright official finds it hard to settle a family quarrel." It is completely unnecessary to make a law to prevent young love. Laws should discipline measurable and detailed acts but not intangible affection, not only because there is no standard to measure this affection, but also because there is no feasible method to enforce such a law.

Whatever next? Personally, I'm in favor of a law against death. Heck, you might as well pass a law to limit climate change ... oh, wait ...

Leaders from the world's emerging economies and G8 countries have agreed to limit global warming to within 2 degrees Celsius
