[citation needed] In 1998–99 Junior Grand Prix (JGP), the pair competed in one event and won the gold medal.

They repeated with a bronze medal at the 2003 Four Continents Championships and improved their placement at the 2003 Worlds, finishing sixth.

Zhang Dan fell on it during the free skate and suffered an injury, but chose to finish the program.

ISU rules say that the program can be continued if the referee agrees the stoppage was due to a valid reason, such as injuries or equipment failures.

They won the silver medal, placing ahead of defending Olympic medalists Shen Xue and Hongbo Zhao.

Before the 2010–11 season began, Zhang Hao broke his finger, forcing the team to pull out of their two Grand Prix assignments.

[6] The Zhangs returned to competition during the 2011–12 season, winning silver medals at the 2011 Skate America and the 2011 Cup of China.

In 2008, she was 1.63 m and in October 2009, she reached 1.675 m.[7] In August 2011, she was the tallest female in elite pair skating, being 1.695 m in height.

[6] Zhang Dan's height proved to be a challenge for the pair, and on May 6, 2012, it was announced that their partnership had ended and she was retiring from competition.

[2] This would mean that during the 2001-02 season she was 14 and too young to compete in senior events such as the Four Continents where they won bronze, as well as the Olympics and World Championships.
