During her competitive career, Dong competed under a passport that gave her date of birth as 20 January 1983. However, when she was certified to work as a technical official at the 2008 Summer Olympics, she was registered with a 23 January 1986 birthdate. In addition, Dong gave the same date of birth on her CV. The 1986 birthdate would have made her 13 in 1999 and 14 at the Olympics – two years below the minimum age required by the International Federation of Gymnastics.
