During the 2000 summer Olympics, Chinese gymnast Dong Fangxiao won the bronze. Ten years later, she was stripped of her medal when it was discovered that she was only 14 during the 2000 Games. According to Olympic rules, athletes must be 16 or over to compete. And this isn't the only time that suspicions have been raised about the age of Chinese gymnasts. During the 2008 Olympic Games, Chinese female gymnasts, He Kexin and Jiang Yuyuan, came under scrutiny for their youthful appearance as well as comments made by a Chinese official, but when the Chinese government produced passports showing the girls' ages as 16, they were allowed to compete.
