Twice | Tzuyu | Chou Tzu Yu (저우쯔위/주자유)

Tzuyu (Hangul: 쯔위) is a Taiwanese singer-songwriter under JYP Entertainment. She is the maknae of the girl group TWICE.

In 2012, she was seen by talent scouts at the MUSE Performing Arts Workshop in Tainan and traveled to South Korea in November that year to become a K-pop trainee. After more than two years of training, she appeared on the South Korean reality show Sixteen in 2015, during which she was chosen as one of the nine members of the girl group TWICE.

Tzuyu debuted as the maknae of TWICE on October 20, 2015, with the extended play (EP) The Story Begins.

In November 2015, Tzuyu appeared with Twice on the Korean variety show My Little Television. She introduced herself as Taiwanese and held the flag of Republic of China (Taiwan) alongside that of South Korea. Mainland Chinese internet users reacted angrily towards Tzuyu's actions due to the political rift between the two countries. Soon after, Twice was barred from Chinese television and Tzuyu was pulled out of her endorsement with Chinese communications company Huawei. Meanwhile, her agency, JYP Entertainment, released a video showing Tzuyu reading an apology.

Tzuyu's apology sparked a furore among the Taiwanese public on election day. The incident gained international attention as it was believed to have affected the 2016 Taiwanese general election. A survey found that Tzuyu's video apology affected the decision of about 1.34 million young voters.
