Career
On February 14, 2011, Xu"s age became the subject of controversy. Although her International Skating Union bio lists Xu as born on July 28, 1988, a Chinese skating association website suggested she was born on July 29, 1990, but it disappeared from the website by February 15. On February 17, the International Skating Union said there were no discrepancies in terms of the birthdates listed on Xu"s passport, International Skating Union registration forms and the Chinese Olympic Committee"s website.
