Chou Tzu-yu (born June 14, 1999), known as Tzuyu, is a Taiwanese singer based in South Korea and member of the K-pop girl group Twice, formed under JYP
Entertainment.
In 2015, a televised appearance in South Korea in which she was shown holding the
Republic of China flag sparked a controversy in China. A video of Tzuyu apologising for the incident, subsequently released by JYP
Entertainment on January 15, 2016, sparked further outrage in Taiwan.
