Xia (or Xin) Xinfeng, from Maolou in the central Chinese province of Henan, has been sentenced to death for killing Mao Ansheng, her childhood sweetheart, with a kiss. They had sworn an oath that if either were unfaithful, they would have to die. Xia took action when she saw her man talking to a woman in a way that made her suspicious. They had arranged to meet the next day at a public bathhouse. She filled a plastic pellet with rat poison, hid it under her tongue, and while they were kissing, nudged it into his mouth. Failing to notice, Mao swallowed it and died shortly afterwards.
