A Chinese Story

I have no idea whether this is a true or fabricated story. Never the less, it was a story that if true still astounds me. I don't recall where exactly, but in a specific China area there was a major epidemic going on with an outbreak of malaria. The Chinese government issued a statement to its citizens. "If you all consider yourselves honorable true Chinese citizens, you will all abide everyday the following instructions. You are to kill at least 10 mosquitos everyday. If you wish to kill more, fire away, but you must kill everyday at least 10 if you consider yourself to be a true, honorable Chinese citizen." China's massive population then wiped out an entire mosquito generation and the major plaque of malaria came to an end. Anyone Chinese out there who may know if this is a true story?
