In July 2016, a family dinner in China was marked by tension between a divorced couple who were still living together. The woman, identified as Bei, still hoped that she and her ex-husband, Qin, could rebuild their relationship.
But Qin had started seeing another woman. Hurt and jealous, Bei decided to prove that she was a better partner than his new girlfriend.
What followed turned a troubled relationship into a deadly crime.
Bei secretly treated Qin’s underwear with paraquat, an agricultural herbicide. She reportedly hoped the chemical would cause a rash and make Qin believe that his new girlfriend had given him a sexually transmitted infection.
Instead, the poisoning eventually caused fatal organ damage.
Bei and Qin Continued Living Together After Their Divorce
Bei and Qin had divorced about six years before the incident. Despite ending their marriage, they agreed to remain in the same home so they could continue raising their two children together.
The arrangement was difficult at first. Over time, however, the family adjusted to their unusual situation.
Their relationship also changed.
After several years of living together, Bei and Qin reportedly became close again. They developed feelings for each other and began discussing the possibility of getting remarried.
But they never officially restored their marriage.
Qin Started Seeing Another Woman
Several months before the poisoning, Qin became increasingly distant toward Bei.
Bei eventually discovered that he was seeing another woman.
Although Qin was legally free to have another relationship because they were divorced, Bei was deeply hurt. She had believed that their relationship was moving toward marriage again.
She confronted Qin about the relationship, and the disagreement turned into a serious argument.
The tension remained when the family sat down for meals together.
Bei Tried to Win Qin Back
Instead of giving up, Bei decided to show Qin that she could still be the ideal wife.
She began spending much of her time cleaning their home and taking care of Qin’s belongings.
She washed his clothes, picked up after him and prepared meals for the family.
She continued doing this for several days.
But Qin did not respond in the way she hoped.
His lack of reaction frustrated Bei, yet she continued trying to prove herself.
Bei Used Paraquat on Qin’s Laundry
The situation took a much darker turn when Bei began using paraquat on Qin’s clothing.
Paraquat is a highly toxic herbicide. Exposure can cause serious poisoning and damage to multiple organs.
According to the account, Bei’s intention was not initially to kill Qin. She wanted him to develop a rash.
Her plan was for Qin to believe that his new girlfriend had caused the rash through a sexually transmitted infection.
She apparently hoped this would make him distrust the woman and end their relationship.
But the chemical exposure had much more serious consequences.
Qin Became Seriously Ill
Qin continued wearing the contaminated underwear without knowing what had happened.
The chemical came into contact with sensitive areas of his skin and was absorbed into his body.
He eventually developed a painful rash and went to the hospital.
His condition then became much more serious.
He began experiencing breathing difficulties, and doctors reportedly warned that his condition was critical.
His daughter contacted Bei and told her that her father was seriously ill.
That phone call changed everything.
Bei Realized What She Had Done
When Bei heard that Qin might die, she understood that the poisoning could be connected to what she had done to his laundry.
She was overwhelmed by guilt.
Instead of going directly to the hospital, Bei went to the police and turned herself in.
She admitted what she had done.
Two days later, Qin died from the effects of the poisoning. His death was ultimately attributed to organ failure.
Bei Was Sentenced to 11 Years in Prison
Following Qin’s death, Bei was charged with intentional injury.
She was sentenced to 11 years in prison.
The case shows how an attempt to manipulate a relationship can quickly become something far more serious. Bei wanted to make Qin reject another woman. Instead, her actions resulted in his death and ended with her serving a long prison sentence.
The Tragic Consequences of Jealousy
The relationship between Bei and Qin had already been complicated for years. They were divorced but continued living together. They had children together and had even considered getting married again.
But Qin’s new relationship changed that situation.
Bei’s jealousy and desire to win him back eventually led her to make a dangerous decision.
What began as an attempt to cause a temporary health problem ended in a fatal poisoning.
The case is also a reminder that toxic chemicals such as paraquat can be extremely dangerous. Even exposure intended to cause irritation or illness can have severe and potentially fatal consequences.
Conclusion
Bei wanted to prove that she was still the right partner for Qin. Her efforts to clean the house and care for him were followed by a much more dangerous plan involving his laundry.
The paraquat exposure caused serious poisoning, and Qin eventually died from organ failure.
Bei later turned herself in to police and was sentenced to 11 years in prison for intentional injury.
What she intended as a way to damage Qin’s new relationship ultimately destroyed the family she had hoped to keep together.
