In November 2001, at China’s Ninth National Games, a small gymnast from Beijing captured the country’s attention. Newspapers called her “Kang Douzi”—“Little Bean Kang”—and, almost without exception, they described her the same way: just thirteen years old. She cried after a costly fall on uneven bars that may have cost her team the gold. Days later, she rebounded to win the all-around title, throwing herself into her coach’s arms, still unmistakably a child on one of the biggest stages in Chinese sport.
And yet, within a year, that same gymnast had changed. By 2002, Kang Xin was no longer thirteen. According to her official profile, she was sixteen—old enough to compete internationally, old enough to stand alongside China’s senior team at the Asian Games.
How does a gymnast age three years in the span of one?
