[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.

During their free skate, Zhang Dan had a bad fall on their attempted throw quadruple salchow, a jump that was not consistent.

Zhang Dan suffered a bad injury, but chose to finish the program.

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

In the 2007–08 and the 2008–09 seasons, they won silver medals at both the Grand Prix Final and the World Championships.

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.

Zhang Dan eventually became the tallest competing female pair skater.

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

On April 14, 2016, International Figure Skating magazine broke the news of Zhang's new partnership with Yu Xiaoyu.

At the 2016–17 Grand Prix Final in Marseille they won the silver medal behind Evgenia Tarasova / Vladimir Morozov.

[12] In their first Grand Prix event of the season, Yu/Zhang placed second at the 2017 Cup of China after ranking second in both the short program and free skate.

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.
