Mrs. Li had been married for years. She shared a high-rise apartment in Luoyang with her husband and their teenage daughter. They played badminton together on weekends. Then she saw a text on his phone and, in her own words, “knew everything.” She did not confront him. Did not call a lawyer. She hired a mistress dispeller instead, a professional whose entire job is to end her husband’s affair without him ever finding out she knew. Every detail of what happened next was filmed, in real time, by a documentary crew that spent three years inside her marriage.
That decision put her in the middle of a booming, strange, and largely unregulated Chinese industry built around one purpose: making the other woman disappear, quietly, without the husband ever finding out his wife knew, and often without the mistress ever finding out she was the target of a professional operation. The industry has a name for the woman being removed. She is a xiaosan, literally a “little third,” the term used across China for a mistress or the third party in a marriage. And there is now an entire profession, the xiaosan quantui shi, built around getting rid of her.
What a Mistress Dispeller Does
A mistress dispeller is hired almost exclusively by wives to end a husband’s affair without direct confrontation. The industry has operated in China for roughly two decades and shows no sign of slowing. Weiqing Love Hospital, a Shanghai company co-founded by Ming Li and Shu Xin, claims to have served more than a million clients and completed over 100,000 “dispellings” since opening. In 2014 alone, the company says its investigators ended 8,552 affairs. Some husbands, the company notes dryly, had more than one mistress running at once.
The methods are where this stops looking like a service industry and starts looking like an intelligence operation. Dispellers pose as new friends, coworkers, or acquaintances to both the husband and the mistress. They rent apartments near the mistress to build proximity. They buy jewelry and clothing to establish the kind of friendship a stranger cannot fake without spending real money on it. Shu Xin told the BBC his company has “33 ways to dispel a mistress,” though he declined to list most of them, calling them business secrets. The few he did share are strange enough on their own: convincing a husband’s employer to relocate him to another city, or telling the mistress that her lover has a “rotten character” and “nasty hereditary diseases.”
Ming, a Weiqing operative, offered her own preferred method plainly: “Sometimes, I help the mistress find a boyfriend.” The company sets the mistress up with someone else entirely, engineering a new relationship attractive enough to make the affair look like the worse option. It is matchmaking aimed at the person the client wants gone.
The New Yorker’s Jiayang Fan spent time with another Weiqing dispeller, Yu Ruojian, and found the counseling side of the business just as calculated as the infiltration side. Wives are coached like generals running a campaign: buy the husband presents, slip an unexpected romantic note into his suit pocket, learn to project the kind of maturity that will win over a disapproving mother-in-law. One client told Fan she was terrified her husband would discover she had sought help at all. “If he finds out I went to a therapist,” she said, “he’ll think this is a ploy and that I am actually entrapping him with my newly learned techniques.” The entire arrangement depends on total secrecy running in every direction at once, the wife hiding the intervention from the husband, the dispeller hiding her real identity from the mistress, and often the mistress hiding the affair from everyone in her own life.
A Shenzhen firm profiled by That’s Mags ran a case that shows how the coaching and the infiltration work together. A young woman named Zhang was told to act more mature to win back her boyfriend’s respect, while two dispellers worked the other side, inserting themselves into the mistress’s social circle and planting, in the company’s own words, “the idea that there were better choices” available to her elsewhere. Two and a half months later, the boyfriend suggested reconciling, his mother had been won over by Zhang’s new maturity, and the mistress had moved on. The firm behind it markets itself with a pamphlet titled, without apparent irony, “teaching you how to hold onto love.”
Two Very Different Ways to Pay For It
Clients choose between two distinct approaches, and the price difference reflects how much subterfuge they are buying.
The non-covert option is comparatively direct. Agents coach the wife, sometimes speak candidly with the mistress about the reality of her situation, and work the case in the open. One Chongqing firm, the Jialijiawai Marriage and Family Service Centre, charged a client roughly 150,000 yuan, about £17,000, for exactly this kind of service. It is faster, cheaper, and leaves less room for anyone to later claim they were manipulated, since much of it happens with everyone at least aware something is being negotiated.
The covert option is the one the industry is best known for. It can run past a million yuan, close to $150,000, and involves months of sustained infiltration: renting property near the mistress, engineering friendships, gathering intelligence on her habits and vulnerabilities, and slowly steering her toward leaving on what feels like her own decision rather than someone else’s engineered exit. It costs more because it takes months, and the entire method depends on nobody involved realizing they are being managed. If the operation fails, reputable firms reportedly refund the full fee, since a botched covert job can leave a marriage in worse shape than before anyone intervened, with a mistress who now suspects she was played and a husband who may start asking why.
There is a bitter irony sitting inside the pricing structure. The clients are almost always the wives, and the money that pays for the operation typically comes from a shared household account. The cheating husband, more often than not, funds the effort to end his own affair without ever knowing it.
The Arithmetic That Created the Industry
The conditions that produced this business are structural, not accidental. China’s divorce rate has climbed sharply over the past two decades, rising from around 1.2 million divorces in 2000 to 2.5 million in 2009 and more than 3.6 million in more recent years, with infidelity consistently cited as the leading cause. Women in Chinese divorces still routinely leave with a smaller share of marital assets than their husbands, and divorce carries a social stigma that falls disproportionately on women rather than men. A wife facing an unfaithful husband is often choosing between two genuinely bad options: stay in a marriage she cannot trust, or leave and accept a worse financial and social position than the man who betrayed her in the first place.
Having a mistress, meanwhile, has become something close to a status marker among a certain class of ambitious Chinese men, an unspoken accessory to visible financial success rather than something purely hidden or shameful. That combination, rising infidelity treated in some circles as a lifestyle signal, and a legal and cultural system that punishes wives more than husbands when a marriage collapses, is what created demand for a service that lets a wife fight back without giving up the marriage, the assets, or her social standing.
Weiqing’s Shu Xin, a former journalist, described the mistress arrangement with a bluntness that borders on clinical. “Mistresses are global,” he said. “But specifically in China they are kept women. The husbands, often rich, pay for luxury apartments, cars and luxury products.” His clients, he added, mostly do not want a divorce. “Some women do not want to divorce out of fear of getting into financial difficulty. They just want to get rid of the mistress. That’s where we come in.”
A lawyer named Zhu, interviewed by AFP about the legality of the practice, confirmed that Weiqing and firms like it are not breaking Chinese law. He also did not pretend the industry was clean. “There are many problems,” he said. “Invasion of privacy, the relationship between the mistress and the investigator is based on deceit. There is the risk that people’s feelings get hurt.” Legal does not mean uncomplicated, and nobody running these firms seems especially interested in pretending otherwise.
The Documentary That Brought This Into the Open
The industry stayed largely hidden from outside scrutiny until filmmaker Elizabeth Lo spent three years, starting in 2021, embedded with a dispeller known to her clients as Teacher Wang. The resulting documentary, Mistress Dispeller, follows a real case from Luoyang: Mrs. Li, her husband, and Fei Fei, the mistress, an entrepreneur from a neighboring city who had no idea for most of the process that she was the target of a professional operation.
Teacher Wang’s method in the film is a case study in patient social engineering. She meets Mrs. Li’s husband under the guise of wanting badminton lessons, since he plays the sport well and the pretext gives her a plausible reason to be in his life. A casual game becomes a dinner invitation, engineered down to the last detail by Wang and Mrs. Li working together. Wang eventually gets herself introduced to Fei Fei as a friend, and quietly begins working to convince her, much like the Shenzhen case, that better options exist elsewhere. Both the husband and the mistress agreed to appear in what they were told was a documentary about modern dating, and only learned its true subject after filming concluded, at which point they had to re-consent to its release before Lo could show it publicly.
The film was shortlisted for the 2026 Academy Award for Best Documentary Feature and won the Author Under 40 Award and the NETPAC Award at the Venice Film Festival. Critics have described it as unnervingly even-handed, refusing to cast the wife, husband, or mistress as a villain, and lingering instead on how ordinary the loneliness underneath the entire arrangement turns out to be once the subterfuge is stripped away. One especially telling detail from the finished film: even Teacher Wang, a woman who has run this playbook on countless clients, seemed unsettled by the final confrontation Lo managed to orchestrate between all three parties. “Normally,” Wang said, “nobody is willing to do this.”
What This Business Sells
Strip away the intrigue and the industry is selling something quite specific: the preservation of a marriage without the wife ever having to have the conversation that would normally define a marital crisis. Nobody confronts anybody directly. The husband typically never learns his wife knew about the affair at all. The mistress typically never learns she was managed out of the relationship by a paid professional working a script. The dispellers themselves describe a job that requires acting, patience, and a kind of manufactured intimacy that has to feel completely real to the person on the receiving end of it, because the moment it doesn’t, the entire operation collapses and the client’s money is gone along with any chance of a quiet resolution.
It is, by any conventional definition, an industry built on sustained deception, and it thrives because divorce in China still costs women more than staying married to a man who cheated on them. The mistress dispeller does not fix that underlying arithmetic. It just gives a wealthy enough wife an expensive, elaborate, and psychologically sophisticated way to route around it, using the cheating husband’s own money to pay for the privilege.
What makes the whole arrangement so uncomfortable to sit with is how rational it is once you accept the premise. If the legal system offers a worse outcome for leaving than for staying, and staying requires removing a third person from the marriage without triggering the confrontation that could end it anyway, then hiring a professional liar to do that removal quietly is not madness. It is simply the most efficient available option inside a system stacked against the wife from the start. The mistress, meanwhile, generally never gets to make an informed choice about any of it. She is befriended, studied, and steered, and in the better-case scenarios, quietly introduced to someone new before she ever finds out why her old relationship suddenly stopped feeling worth it.
