The Tzuyu Taiwan Flag Waving Incident began in late 2015 when Chou Tzu-yu, a Taiwanese member of the K-pop group TWICE, held a small flag of the Republic of China on a Korean variety show. This seemingly minor action sparked massive outrage among Mainland Chinese netizens, leading to a viral controversy that resulted in a public video apology from the teenaged singer. In the world of memes, this event is frequently referenced to depict moments where a harmless action triggers an overwhelming and unintended backlash. It remains a significant example of how celebrity culture, social media, and international politics can collide in an instant.
