Yi’An Music Club.

Yi’An Music Club (易安音乐社) is a Chinese boy group managed by Original Plan and currently made up of Chi Yi and Yu Muyang. The group debuted on March 30, 2017, with the single “Chitty Bang Bang.” Its original lineup consisted of He Luoluo, Fang Xiangrui, Lin Mo, Chi Yi, Zhan Yiwen, Fu Yunzhe, and Yu Muyang, while Mo Wenxuan joined at a later date. Built around the fictional setting of “Yi An Middle School,” the project follows a rotating membership format in which students may enter or leave the music club. In 2018, Xiangrui and Yiwen departed from the group; Xiangrui later pursued acting under the name Zhou Yiran, and Yiwen went on to debut with TNT. Other former members also continued their careers elsewhere, with Luoluo joining R1SE, Yihang debuting in IXFORM, and Lin Mo becoming a member of INTO1. Fu Yunzhe sought to end his contract in 2023 and has since returned to private life under his birth name, Fu Yongjie.
