 The story is based on a series of posts under the title of "This Is How I Punish A Cheating Man And His Mistress" (《看我如何收拾贱男与小三》), which has over one million hits. "

 It echoes some of contemporary China's own problems, such as corruption, money, ambiguity and morality," says Brice Pedroletti in his review on "The Guardian"
