A new industry has emerged in China, helping husbands and wives to separate their unfaithful spouses from their lovers.
It is called mistress dispelling, in which clients often pay tens of thousands of dollars to see off unwanted love rivals.
A middle-aged woman (Mrs X) wants her name to remain secret but she is happy to talk about her experiences as a client of the Weiqing Love Hospital, Shanghai's best-known Mistress Dispeller service.
In a quiet, quavering voice she tells that her relationship with her husband has emerged from a crisis stronger than it was in the past.
"When I discovered the affair, I confronted my husband," Mrs X says. "We fought bitterly and I kept on asking him, 'Why - why, when I have followed you so many years?' At first he expressed guilt. But after all the fighting, he just didn't want to talk to me anymore. That's when I sought help."
Ming Li, a co-founder of Weiqing, counsels women like her about the secrets of successful wedlock, and how to prevent a husband's attentions from wandering, says a BBC report.
Along with another co-founder Shu Xin, Ming Li has been running the Love Hospital for 17 years, seeing more than a million clients.
Both put on an effervescent display, keen to describe the joyful possibilities of their brand of marriage guidance, and also the secret weapon - mistress dispelling.
"We have 33 ways to dispel a mistress," Shu Xin explains. "In marriage there are all kinds of problems. And one is having an affair. It's very serious, bad for the family and bad for the stability of society".
