They continued the season with a bronze medal at the 1999 Chinese National Championships. The following season, they competed in two 1999–2000 JGP events, medaling in both. They qualified for the final, where they finished fifth. That year, they were second at nationals and finished fourth at Junior Worlds.

The following three seasons, they were very successful at the junior level. They won all their Junior Grand Prix events, including the 2000–01 JGP Final and the 2001–02 JGP Final. They also competed in the 2001 Junior Worlds and the 2003 Junior Worlds, winning gold both times. At the Chinese National Championships, they placed third in both 2001 and 2002, before winning their first national title in 2003. Their first senior international was the 2002 Four Continents Championships, where they won the bronze medal. The same season they competed in the 2002 Olympics, placing 11th, and the 2002 Worlds, placing 9th. The following season they competed in their first two senior Grand Prix events, placing fourth at both events. They repeated with a bronze medal at the 2003 Four Continents Championships and improved their placement at the 2003 Worlds, finishing sixth.

2005–06 season: Olympic medalists

This section of a biography of a living person does not include any references or sources. (December 2014)

Zhang and Zhang went into the 2006 Olympics as medal contenders. They had planned a throw quadruple salchow jump for the free skate, a jump which had not yet been landed in competition. Zhang Dan fell on it during the free skate and suffered an injury, but chose to finish the program. There was a minor controversy about finishing the program because while Zhang Dan had been lying on the ice from the fall, the referee had stopped the music, and the Zhangs took a certain amount of time to restart 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. Once the referee has approved a continuation, the skaters are given two minutes to continue the program from the point where the music stopped. Zhang regrouped within this period and was able to finish the program. They won the silver medal, placing ahead of defending Olympic medalists Shen Xue and Hongbo Zhao. At the Worlds, they won the silver, behind Pang Qing and Tong Jian.

Later career

In the 2006–07 season, Zhang and Zhang placed first at Skate Canada, second at the NHK Trophy, and would go on to win the bronze medal at the Grand Prix Final. They placed 5th at the 2007 World Figure Skating Championships later that season. In the 2007–08 and the 2008–09 seasons, they won silver medals at both the Grand Prix Final and the World Championships. They also set the world record score in the short program twice: 71.60 points at the 2007 Trophée Éric Bompard and 74.36 points at the 2008 World Championships.

At the 2010 Winter Olympics, the Zhangs placed fifth. They also finished fifth at 2010 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. He also dealt with some shoulder and cervical vertebra problems.^[3] The Zhangs returned to competition during the 2011–12 season, winning silver medals at the 2011 Skate America and the 2011 Cup of China. They finished 4th at the 2011–12 Grand Prix Final.

Zhang Dan eventually became the tallest competing female pair skater. In 2008, she was 1.63 m and in October 2009, she reached 1.675 m.^[4] In August 2011, she was the tallest female in elite pair skating, being 1.695 m in height.^[3] 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. Zhang Hao formed a new partnership, while Zhang Dan stated that she would focus on her university studies.^[5][6]
