Before she became the vocal powerhouse of fourth-generation K-pop, Ning Yizhuo was a child performer navigating China's competitive talent show circuit. Born in Harbin—the capital of Heilongjiang province in China's northeast—she appeared on China's Got Talent Season 2 at just eight years old in 2011, demonstrating the bold stage presence that would define her career. By 2015, at age 12, she competed on Zhejiang Satellite TV's Let's Sing Kids Season 3, where her emotional ballad performances and technical vocal range caught the attention of SM Entertainment scouts watching from Seoul.1

The recruitment approach became part of K-pop lore. SM Entertainment contacted Ningning directly through social media after watching her competition videos—a message she immediately dismissed. "After watching the videos where I participated in those auditions, SM sent me a direct message on my old social media account," she recounted on Lee Mujin Service in 2024. "Their message was a shady one... it looked like a typical scam." She didn't reply at first. But unlike her future groupmates—Karina received an Instagram DM she thought was fraudulent, Winter was approached at a dance festival where the scout refused to name the company—Ningning's path began entirely through her Chinese performance footage. Only Giselle took SM's traditional Saturday audition route.2

At just 14 years old, Ningning flew to Korea with her mother, spent a week navigating the unfamiliar industry landscape, and signed her contract with SM Entertainment. On September 19, 2016, she was publicly introduced as a member of SM Rookies—the company's pre-debut training team—becoming the first Chinese female trainee revealed since f(x)'s Victoria years earlier. Winter later recalled that when she joined SM in 2017, Ningning had already been disclosed as an SM Rookie: "I felt like I was watching a celebrity."3

Ningning's trainee period—approximately four to five years—was the longest among aespa's members. During this time, she appeared on the "Rookies Princess: Who's the Best?" segment of the program My SMT in 2016, and recorded several covers for the Korean animated TV program Shining Star in 2017. These appearances showcased her developing vocal technique while building anticipation among fans tracking SM's trainee roster.4

On October 28, 2020, during an SM Entertainment press conference, Ningning was revealed as the third member of aespa—described by the company as "an 18-year-old Chinese member with an outstanding voice." The group debuted on November 17, 2020, with "Black Mamba," which achieved 21.4 million views in its first 24 hours—setting the record for the most-viewed debut music video by a K-pop group. As SM Entertainment's first girl group since Red Velvet in 2014, aespa's innovative metaverse concept—featuring virtual avatar counterparts called "æ"—positioned them as pioneers of K-pop's fourth generation.6

The breakthrough came in May 2021 with "Next Level," a remake of A$ton Wyld's track from the Fast & Furious soundtrack. The song became aespa's first top-two hit in South Korea, dominated MelOn's 24Hits chart—making them the first SM artist and first fourth-generation group to reach number one on the platform, even surpassing BTS's "Butter." The song also made aespa only the third K-pop girl group to chart multiple songs on the Billboard Global 200, following BLACKPINK and ITZY. "Next Level" later earned the daesang for Song of the Year at the 19th Korean Music Awards.7

Their debut EP, Savage (October 2021), pushed boundaries further. The title track achieved a "perfect all-kill" on Korean charts—reaching number one simultaneously on the real-time, daily, and weekly components of iChart, Melon, Genie, FLO, Bugs!, and Vibe—making aespa the first fourth-generation act to accomplish this feat. The EP debuted at number 20 on the Billboard 200, setting the record for the highest-charting debut album by a K-pop girl group.8

In April 2022, aespa performed at the Coachella Valley Music and Arts Festival as part of 88rising's main stage showcase—becoming the third K-pop girl group invited to the festival and the fastest to receive such an invitation after debut, just 18 months after "Black Mamba." "It's our first time performing in front of a large audience like this. We're so happy to be here at Coachella," Ningning told the crowd. The performance included their biggest hits and the premiere of "Life's Too Short."9

Ningning's individual artistry flourished alongside group activities. In May 2022, she released "Once Again" with fellow member Winter as the OST for tvN's hit drama Our Blues, joining a star-studded soundtrack lineup including Taeyeon and 10CM. The acoustic pop ballad showcased her softer vocal color and topped iTunes charts in the Philippines, Thailand, and Vietnam.10

In July 2023, she collaborated with Jay Park on "WYA" (妳在哪裡), a surprise release for the Chinese survival show The Next 2023, where both served as mentors—Jay Park as a regular mentor, Ningning as a special guest. The performance went viral on social media, highlighting Ningning's appeal in the Mandarin music market and demonstrating her versatility beyond aespa's signature hyperpop sound. A remix featuring PH-1, Lexie Liu, ØZI, and Masiwei followed in August.11

On February 8, 2024, Italian luxury house Versace announced Ningning as their Global Brand Ambassador—her first solo partnership with a major fashion brand. Creative director Donatella Versace introduced the appointment personally: "Today, Ningning joins our Versace family as a Global Brand Ambassador. She is not only a brilliantly talented star, she is a wonderful person. She has a strong, confident vision, incredible energy and talent and she looks amazing wearing our clothes." Ningning joined fellow K-pop ambassador Stray Kids' Hyunjin and actress Anne Hathaway in representing the house.12

"Versace has always been about pushing boundaries of creative expression and championing those who are confident to express themselves, especially in the music world," Ningning said upon the announcement. "That is why being a Versace brand ambassador is so exciting for me." She subsequently fronted Versace's Kleio Bag campaign in August and starred in the brand's Holiday 2024 campaign video in November. With all four aespa members now representing major global fashion houses—Karina with Prada, Giselle with Loewe, Winter with Polo Ralph Lauren—the group has cemented its status as fashion icons of the fourth generation.13

aespa's commercial dominance reached new heights in 2024. Their first studio album, Armageddon (May 2024), was led by the single "Supernova," which topped Korea's Circle Digital Chart for eleven consecutive weeks—a historic achievement that earned the group Song of the Year at both the 2024 MAMA Awards and 2024 Melon Music Awards. The track marked aespa's first top-ten entry on the Billboard Global Excl. US chart.14

In October 2024, their fifth EP Whiplash made aespa the first K-pop girl group with six consecutive albums in the Billboard 200's top 50. The title track reached number eight on the Billboard Global 200—the group's first top-ten entry on the main global chart. Earlier that month, Ningning released "Bored!" as part of the special digital single SYNK: Parallel Line, an R&B dance track she co-wrote, showcasing her growing involvement in songwriting.15

Beyond her professional achievements, Ningning has been candid about personal challenges. In 2023, during an appearance on BamBam's YouTube show Bam Home, she revealed that she has ADHD, discussing how it affects her ability to focus on hobbies like drawing and reading despite her love for them. In an interview with Vogue China, she disclosed having undergone eye surgery as a child and that she "can barely see" with her right eye—a vulnerability rarely shared by K-pop idols navigating an industry built on visual perfection.16

Her mother, a musician, remains her role model. "My mother is my role model in life," Ningning has said. "She's really independent and strong, and she takes good care of those around her. She's also cool-headed in any situation. She's the strongest woman I have ever met." As aespa continues to redefine fourth-generation K-pop with their innovative metaverse concept and commercial success, Ningning remains the group's vocal anchor—a performer whose journey from Chinese talent shows to global stages exemplifies both the internationalization of K-pop and the industry's intensifying search for extraordinary voices.
