Meet The Mistress Killer: Who Helps Wives Get Vengeance From Cheating Husbands..(Read Details)

But while Zhang Yufen’s private investigation work is about seeking revenge for wives who have been left by their husbands, it isn’t with the intention of wiping them out completely.After discovering her husband was cheating, Zhang, who lives in China’s Shaanxi Province, decided to find out who his mistress was to force him to provide financial support for their son.

She did the research herself, but little did she know her detective work would prove so successful it would eventually become her livelihood (although she insists she only charges expenses).

Her first case came in the nineties after an elderly woman approached her to say her son-in-law was cheating on her daughter.She said the adultery had driven her to attempting suicide but she had no evidence to prove it so needed Zhang’s help.

But before she could begin to work on the case, the daughter tragically took her own life, the private investigator told the Global Times, she told the woman, ‘that I would ruthlessly exterminate those men’.She has since taken on thousands of cases and set up her own agency, the Alliance Against Mistresses.But while many of those have been with the sole intention of building cases for court, some have reportedly spilled over into violence too.

According to the same website, the first case in which the mistress she was helping beat her husband came after the pair tracked him down in the street.

She said the woman barged into her husband kicking him and breaking his glasses.

‘We beat the woman into the middle of the street, causing a traffic jam. There were lots of people standing there, watching us beat the woman,’ she added, claiming police turned a blind eye to the incident.‘The police officer told me that he “didn’t see what’s happening.” When I heard this, I knew it’s OK. So I kept beating the mistress.’

Like the one above, videos of other women exacting revenge on their husbands have emerged online, including one last week in which a wife was said to be beating his mistress.

But, despite being threatened with violence and arrest herself, and having seen cases thrown out by supposedly biased judges, she has also had successes.

According to the Washington Post, Zhang helped a woman whose husband had divorced her and been awarded the family land in court.

But with the woman’s help, Zhang and other wronged wives she was working with tracked him for two years eventually tracking him down and gathering evidence of infidelity and corruption.

The wife, who wishes to remain anonymous, said: ‘It was really difficult because he had a car, and we had to move on foot and by taxi.

‘But Zhang and the other wronged wives stood up for me. Come heavy snow or scorching sun, they followed him, they never gave up.’

Zhang’s success now sees her received up to 100 calls a day from women seeking her help.

One day after an interview on the Beijing Television Station, dozens of women gathered downstairs to ask her for advice and guidance.

The reason for her popularity?As one woman, who Zhang helped, called Tang, put it, the law doesn’t do enough to protect wives.‘You need to have evidence in court. But how do you get the evidence? They don’t help you to collect it,’ she said.
