Jieqiong / Kyulkyung
Zhou Jieqiong helped build the original eleven-member I.O.I. This page follows the whole career—not only the reunion clip currently eating the timeline.
Early life and the road into entertainment
Jieqiong moved from China to South Korea as a teenager to train under Pledis Entertainment. On Produce 101, her dance precision, pipa performance, and unmistakable camera presence made her one of the season’s most recognizable trainees.
Produce 101 and the original I.O.I chapter
I.O.I formed through the first season of Produce 101 and debuted on May 4, 2016. The contract was temporary by design, which meant the group learned to perform, promote, split into a seven-member unit, return as eleven, and say goodbye while the countdown clock remained visible.
Jieqiong / Kyulkyung belongs to the full eleven-member lineup: Lim Nayoung, Chungha, Kim Sejeong, Jung Chaeyeon, Zhou Jieqiong, Kim Sohye, Yoo Yeonjung, Choi Yoojung, Kang Mina, Kim Doyeon, and Jeon Somi. A promotion lineup can change. The historical membership does not.
After I.O.I: the career did not freeze in 2017
After I.O.I, she debuted with PRISTIN and later developed a solo acting and music career in China. She did not participate in the nine-member 2026 LOOP recording and promotions because of prior commitments. That is an attendance note, not a rewrite of I.O.I into a nine-member group.
2026: I.O.I : LOOP and “Suddenly”
I.O.I returned for its tenth anniversary with the six-track mini album I.O.I : LOOP and the title song “Suddenly.” Nine members participated in the new recording and promotions. Mina and Jieqiong were unable to join because of prior commitments; neither was announced as having left the group.
The project matters because the members returned with adult careers, different companies, and creative credits of their own. Somi co-wrote “Suddenly,” while other members contributed elsewhere on the album. This is not eleven rookies waiting for a label to tell them who they are anymore.
Performance identity
The correct sentence is “Jieqiong could not join this promotion.” The incorrect sentence is “I.O.I has nine members now.” Fandom archives should know the difference.
RaeRae take: Reunion coverage gets lazy when it treats every member as a before-and-after photo. The interesting story is what each woman learned elsewhere—and what becomes visible when they stand together again.
Fandom notes without rewriting history
- Fandom: U&I.
- Full membership: Eleven. Always distinguish membership from a specific promotional lineup.
- 2026 promotion: Nine members recorded and promoted most of LOOP.
- Archive track: “Goodbye With A Smile,” recorded in 2016, preserves all eleven voices.
