Wu's parents first sent him to the pool when he was four years old as an exercise for weight-loss. He first decided to dedicate himself to swimming while watching swimming in the 1996 Olympics; the best result for Chinese men's swimming was 4th place in 50m freestyle, while Chinese women's swimming got gold. Wu said to his father that he wanted to be the first Chinese man to stand on the podium for Olympic swimming. Wu's father died of a heart attack in 2003 while meeting Wu to bring him home for the weekend after practice.
Career
He had excellent times at the National Games and Asian Games. In fact, he has brought hope to China's swim team since first joining it. He was one of the youngest swimmers on the team when he joined. At the 2004 Athens Olympics, when he was only 17, Wu Peng made the 200 m butterfly final and became the only Chinese swimmer to finish in the top eight at the games. It was only Wu's first Olympics, and the team was satisfied with his performance. At the 2006 short course World Championships in Shanghai, Wu won the 200 m butterfly in a championships record. He also won the bronze medal at the 2005 World Long Course Championships in Montreal, and the silver behind Michael Phelps at the 2007 World Long Course Championships in Melbourne, both times at 200 m butterfly. At the Beijing Olympics, he carried the nation's hopes for a breakthrough in swimming. Although making it to the finals, he managed a joint fourth with the New Zealand swimmer Moss Burmester. He suffered an injury in 2009 and could not make it to the WorldLong Course Championships to try for the podium once again. Wu himself has said that if he were to medal in the London 2012 Olympics, he would consider his career to have been full and satisfying. Wu Peng defeated Michael Phelps in the 200 fly in consecutive events, at the Michigan Grand Prix and Charlotte UltraSwim, in 2012 ending Michael Phelps' streak of 60 wins in nearly 9 years.
