‘Mistress killer’, ‘China’s top ladies’ detective’ or ‘Terminator of extramarital affairs’ are just some of the nicknames that Zhang Yufen has earned during the 15 years she has dedicated to helping cheated wives gather evidence on their husbands’ affairs and helping them exact revenge on their mistresses.
Zhang Yufen’s war on adultery is fueled by her personal experience. During the late 90’s her husband, who worked in the district taxation bureau in the city of Xi’an, started having an affair and eventually told her that he was seeing someone else and didn’t want her anymore. He took their most valuable possessions, cleaned out their joint bank account and he was gone. The news was devastating and Zhang remembers curling up on the couch and crying for a week. But after the news finally sunk in, she decided that the only way to receive justice was to track down her husband and his mistress and gather evidence about their affair. Little did she know that she would spend the rest of her life doing the same thing for other cheated wives.
Zhang spent five long years tracking down her husband multiple times, as he moved to different locations every time he caught her snooping around. But in 2007, after gathering enough evidence about his infidelity, she was finally granted a divorce and became entitled to a payout from her former spouse. At that point, she had already made a name for herself as a detective helping other wives expose their cheating husbands and their mistresses.
