Who: Dong Fangxiao
Olympics: Sydney 2000

Ten years after helping the Chinese women's gymnastics team win a bronze medal, Dong Fangxiao was found to be 14 when she competed. The minimum age for Olympic competition is 16. The US women's team ended up being awarded bronze medals in place of China. Speaking of underage Chinese gymnasts, isn't it about time to look into the babyfaced 2008 team?
