Hyoyeon (효연) is a Korean pop singer. She is a sub vocalist and main dancer for Girls’ Generation, and was a trainee with SM Entertainment for six years and one month. She is most known for her popping, waving, and Hip-hop dancing techniques that she learned from the Winners Dance School while she was a trainee. Prior to her debut, she traveled to Beijing, China in 2004 with Super Junior’s Siwon to learn Mandarin and more about Chinese culture.
Hyoyeon was born in Incheon, South Korea on September 22, 1989. She is ambidextrous and grew up with her parents and her younger brother Kim Min Gu. She auditioned for SM Entertainment at the age of 11 through SM 2000 Casting System. Hyoyeon herself said, she had no intentions to audition, but her mother was a fan of SM Entertainment’s boy band H.O.T. and brought her to the offices in the hopes, perhaps, of seeing them. She then danced in her audition show. In 2004, she was sent to study Mandarin Chinese in Beijing, China alongside with Choi Siwon. Her Chinese name is 孝渊 (Xiàoyuān) in simplified Chinese characters.
