Girlhood. When I was a girl, there were eight women in the Korean women's singing group and the Korean entertainment company's women's group, including a dance video of pigeons flying. The girlhood consists of eight people: Kim TaeYeon, Li Shungui, Huang Meiying, Jin Xiaoyuan, Quan Yu Ri, Choi Soo Young, Lin Yunya and Seohyun. 20 17 years, the girlhood with an average age of 17 officially debuted with the song "The World of Reunion".
