Xu Bo, a 48-year-old Chinese billionaire and founder of online gaming company Duoyi, has fathered more than 100 US-born children through surrogacy agencies and reportedly hopes they will one day marry Elon Musk’s children to create a sprawling family dynasty, according to social-media posts verified by the Wall Street Journal.Xu, who calls himself “China’s first father,” publicly stated he intended to sire at least “50 high-quality sons.” Duoyi later posted on social media that he had produced over 100 children via US surrogacy.The story ignited on Chinese social media after Xu’s ex-girlfriend, Tang Jing, claimed he had fathered more than 300 children, 11 of whom she said she had raised for years. “That number might even be undercounted, but it’s certainly not exaggerated,” said Tang Jing, Xu’s ex, in a post Nov. 15, according to the India Times.The pair are now engaged in a custody battle over two daughters they share, with Xu claiming his ex owes him tens of crores in expenses he paid over the years and declining to challenge her posts about his hundreds of children.In a video posted in 2022 by an account linked to Xu, footage showed dozens of young boys in a mansion. As the camera panned, the boys leapt from their chairs and rushed towards the cameraman, shouting “Daddy!” in Chinese. “Imagine a bunch of babies rushing towards you—how does that feel?” reads the caption on the video, according to the outlet. “Take a look. Besides your loved one, what’s cuter than children?”A representative for Duoyi told the Journal that “much of what you described is untrue.” The representative, who refused to give their name, did not respond when asked for specifics.Xu’s quest to build a family dynasty was reportedly inspired by Musk, who has been rumoured to offer friends and family sperm in an effort to build his bloodline—a claim Musk has denied. On Weibo, Xu posted fantasies of his offspring one day marrying Musk’s children, according to the Journal.In the summer of 2023, a judge in California handled petitions from Xu to gain parental rights for four unborn children, as well as at least eight other children he had paid for through surrogates. The judge immediately called a confidential hearing, and Xu appeared over video. He told the judge he hoped to sire 20 or more US-born children—boys specifically because they are superior—to one day take over his business. The judge rejected his petition for parental rights, leaving the unborn children in legal limbo and exposing an industry of surrogacy companies helping wealthy Chinese businessmen have American-born children.Many of his children have reportedly lived in a home in Irvine, Calif., and been raised by nannies. Xu told the judge he had not met them yet because work had been busy but said he planned to bring them to China soon.
