During the 2010–2011 season, controversy over age falsification reached the sport of figure skating, after previously being discussed in gymnastics and other sports. On February 14, 2011, questions emerged surrounding nine Chinese skaters. The Associated Press found that birthdates listed on the Chinese skating association's website suggested five female skaters, Sui Wenjing, Zhang Dan, Yu Xiaoyu, Geng Bingwa, and Xu Binshu, were younger than their stated ages, and four male skaters, Han Cong, Zhang Hao, Jin Yang, and Gao Yu, were older. The dates disappeared from the website by February 15. On February 17, the ISU said there were no discrepancies for Zhang Dan, Zhang Hao, and Xu Binshu between the birthdates listed on their passports, ISU registration forms and the Chinese Olympic Committee's website.
