Members Fei and Jia were selected in 2007 (Fei was scouted on her way to dance school, while Jia’s school held auditions). Before their debut, members Fei and Jia appeared in 2PM’s “My Color” music video.

Originally, Miss A were a 5-member group in training in 2009. While still in training, the group flew to China where they appeared in numerous variety shows performing dance routines and songs to showcase themselves to the Chinese audience. As the group had no official name they were widely known to the Chinese audiences as JYP Sisters and the “Chinese Wonder Girls”. However the group had gone through several changes during this period, most notably the exit of member Lim who was re-grouped to join the Wonder Girls, while two other girls decided to withdraw from the group. JYPE then decided to group the two remaining girls, Fei and Jia with JYPE South Korean trainee 15-year old, Suzy Bae who had previous experience as a model for an online shopping mall.

The girls began their first official promotional activities in China as a group by signing up with Samsung China and released a commercial song called “Love Again” for the Samsung Beat Festival. The song has a strong Korean team/influence behind it, as it was written by Korean composer, Super Changddai while the music video was directed by Hong Won Ki. Lee Min Young, a solo artist and a long-time JYPE trainee in America, also made a cameo appearance in the music video. She had auditioned when she was in the 6th grade, and traveled to the U.S., where she trained for 6 years, but came back in 2008 to continue activities in Korea. During her time in New York, she studied at the Repertory Company High School in Manhattan. It was later announced she would be joining the group under her stage name, Min, and will be debuting with the group in South Korea.
