What can you buy with 6 yuan? "A liter of gasoline, a half catty of pork, or ride an air-conditioned bus three times!" But here at Ning Nan's place, perhaps you can only buy a dead mosquito. "I sell them this expensive because I kill them by hand." Since he posted the first online sale information about "mosquito corpses" on June 19th, within 48 hours, this product has already had 200,000 views, and over ten thousand people have purchased the "mosquitoes" that he killed by hand. After becoming popular across various forums, netizens unanimously commented that this was a classic business strategy, one that could even be included in MBA textbooks.
