Xu Huaiwen is one of the most successful female badminton players in the world's biggest events. Xu’s best ranking in the world was the number one published by the Badminton World Federation (BWF) on June 22, 2006. For most of the time, Xu’s ranking has ranged from number three to number eight.

 Born in the badminton-rich country China, Xu started her professional career at the age of eight. She has been on the China National Team for two and half years. Her earlier achievement in China included winning three times bronze medal at China National Championships, and one bronze medal at the Seventh National Sports Games in 1998.

Xu started to play for Germany in 2000 and she began her consistent performance in the open tournaments in Europe and on the international badminton circuit since then. Xu competed in the Olympic Games twice (2004 Athens, and 2008 Beijing). At the 2008 Beijing Olympics, Xu won the fifth place by losing to the world's number one ranked player Xie Xingfang in a close quarterfinal match. Xu has been a women's singles bronze medalist twice at the BWF World Championships (2005 Anaheim, USA; and 2006 Madrid, Spain) and has won the last two European Championships (2006 Holland and 2008 Denmark) over Mia Audina and Tine Rasmussen respectively in the finals. Among Xu's more than twenty national and international singles titles are the super series opens: Scottish (2003), Polish (2003), Dutch (2005), and Swiss (2006) Opens, the Copenhagen Masters (2007), and the last five (2004–2008) German National Championships. Xu was the major player for the Team Germany at the world championships team event Uber Cup, and she helped the team win Bronze Medals twice.

Besides her competition, Xu coaches badminton players at all levels. She taught children and adults groups between the age of 8 to 26 at two badminton clubs in Germany: VFB Badminton Club (2000-2003) and Bischmisheim Badminton Club (2003-2009). In 2007, Xu acquired a coach license at Level A, the highest level in Germany, which qualifies her to train the top professional players.

Xu’s accomplishments lead her to win many honors. In 2006, Xu was named as the best female athlete by the State Saarland of Germany. She received telegraphs from the Chancellors of Germany, Gerhard Schroeder in 2005 and Angela Merkel in 2006, recognizing her success and dedication to the sports. Finally, she was rewarded with Silbernes Lorberrblatt, the highest sports reward of Germany, in 2008. 

When Xu was eliminated by China National Team’s coaches to become the top player in the world because they thought that she was too short to play professional world badminton, Xu determined that she would prove herself one day through her commitment and hard-work. When people asked her why she didn’t quit since Chinese elite coaches already said that she was not suitable for professional games, she always smiled and said:“Badminton is part of my life and career. I want to compete, win and prove myself. Other people can give me up, but I cannot give myself up.” So she kept her words and she made it. Indeed, she achieved her success in a condition that most other people thought she should quit.

 Xu speaks fluent Chinese, German and English.
