BWF profile

Dai Yun (simplified Chinese: 戴韫; traditional Chinese: 戴韞; pinyin: Dài Yùn; born 22 November 1977) is a Chinese former badminton player.^[1]

At the beginning of the century Dai was ranked among the world's leading women's singles players, most of whom were her fellow countrywomen. Her titles included the Chinese Taipei (1999), Malaysia (1999), Thailand (1999, 2003), and Swiss (2000) Opens. She was a highly effective member of consecutive world champion Chinese Uber Cup (women's international) teams in 1998, 2000, 2002. However, in badminton's three most prestigious competitions for individual players – the All-England Championships, the World Championships, and the Olympic Games – victory eluded Dai. She was a runner-up to Chinese teammates at the 1999 and 2000 All-Englands. At the 1999 World Championships in Copenhagen she reached the final only to lose the closest of matches to Denmark's Camilla Martin. At the 2000 Olympics in Sydney she was beaten by Martin, again, in the semifinals, and then lost a close bronze medal match to fellow countrywoman Ye Zhaoying. Dai's results slipped somewhat after 2000, and she retired from international play in 2004.

She is married to another former Chinese badminton player, Liu Yong.^[2]
