Women's artistic gymnastics
China entered Dong Fangxiao into the 2000 Olympics under a birth date of 20 January 1983, which would have made her 17. However, when she obtained accreditation to work as a technical official at the Beijing Olympics eight years later, she gave her birth date as 23 January 1986, which would have made her 14 and too young to compete. In 2010, the International Gymnastics Federation concluded that Dong had been born in 1986 and revoked the bronze medal she won with the Chinese team in Sydney.
