The businessman, named as Mr Fan and said to be from the city of Qingdao on the east coast, invited the five mistresses, who had all previously learned of each others' existence, to dinner, according to a local newspaper, the Peninsula Metropolitan News.
Along with a friend, who worked for a model agency, and inspired by reality television shows, he then laid on a competition for them, according to the report.
One woman was eliminated during a "looks round" and two more, who worked as clerical officers in his company, during a speech round. The final round was a drinking competition.
The story came to light after the first loser, to show no hard feelings, took all four other women and the businessman out for a drive – upon which she drove over a cliff in the hope of taking revenge on all of them. As it turned out, she was the only one who died.
