To try to determine the probability of those name repetitions being a coincidence, Cary checked two databases of Chinese names and consulted with Yi Fuxian, a professor of Chinese demography at the University of Wisconsin–Madison. The name Qiu Daibing—or 邱代兵 in Chinese characters—turned out to be a relatively unlikely name to show up twice just by chance, he says. The surname 邱 alone, Yi confirmed to WIRED, represents just 0.27 percent of Chinese names, and in combination with the specific 代兵 given name would represent a far smaller percentage.
