SING女團, also known as S.I.N.G. or SING Girls, debted on August 10, 2015, as a ten-member girl group. SING is an acronym for “Super Impassioned Net Generation”. Eventually, the group would go through a few member changes, three members would participate in the Chinese edition of the Korean competition show Produce 101, with member Lai Meiyu eventually becoming part of the group Rocket Girls, and member Lin Jinyi left due to health reasons.

Although many of their early tracks were stereotypically cute and pop, in 2017, they transitioned into music that incorporates traditional Chinese elements, which they are now known for, although they still release modern pop tracks.

Today, although the group had members leave, the current lineup consists of Sophie (Qin Yu 秦瑜), Haha (Lin Hui 林慧), Debbie (Jiang Shen 蒋申), Sunny (Lei Meiyun 赖美云), Valentina (Xu Shiyin 许诗茵), Pink (Chen Li 陈丽), Miko (Wu Yao 吴瑶 ), and Jessica (Bian Li 边丽).
