On February 14, 2011, the Zhangs' ages became the subject of controversy. Although his International Skating Union bio lists Zhang Hao as born on July 6, 1984, a Chinese skating association website suggested he was born on February 6, 1982. This would mean he was too old to compete in junior events during the 2002–03 season, such as the 2003 World Junior Championships where they won gold. His partner's age also came under scrutiny. Her ISU bio states that she was born on October 4, 1985 but the Chinese website suggested she was born on that day in 1987, meaning she was 14 and too young to compete in senior events during the 2001–02 season, such as the Four Continents where they won bronze, as well as the Olympics and World Championships. The dates disappeared from the website by February 15. On February 17, the ISU said there were no discrepancies for the Zhangs in terms of the birthdates listed on their passports, ISU registration forms and the Chinese Olympic Committee's website.
