Cantonese (Jyut Jyu) is a language prevailing in the Guangdong province of China, Hong Kong, Macau, and ethnic Chinese groups in Southeast Asia and North America. It evolves with the engagements of the authoritarian government and globalization over time. Cantonese in China is special because it remains strong under the constant suppression from the administration and the continual interactions between the natives and migrants. However, the concern about Cantonese dying among the natives has been increasing in recent years. The speaking population, the imposed language policy, and the economy at least determine Cantonese's life. In particular, the economy is also a window to examine the central-local relations in China due to the leading roles of the Pearl River Delta, Hong Kong, and Macau in China's economic growth. Therefore, the struggles of local language between the younger generation and the Communist Party via the Internet are exposed. The book intends to explore the rising of a potential language community around the globe that speaks Cantonese by analyzing the usage and images of Cantonese of a popular TV show on YouTube, discussion groups on Baidu Tieba and Facebook, and talk shows on Bilibili with content analysis, interviews, and cases studies. Through this research, the relations between language and collective identity will be presented in an innovative way. "Remaking a Global Cantonese Community with Television and Social Media" has something to offer everyone, regardless of age or background. For those residing in mainland China, it's a journey back in time. Older Cantonese speakers will reminisce about their childhood, with memories of delicious Cantonese food, playful children's songs, and cherished customs. Even those who aren't native Cantonese speakers will recall the Cantonese TV shows, movies, and music that colored their youth. Younger readers will find familiar elements in the short videos they currently enjoy. For language preservation advocates, this book sheds light on Cantonese speakers' efforts to protect their native language and the challenges they face. For readers outside of mainland China, it offers insights into the country's internal changing landscape, especially grassroots practices and identities. By blending the disciplines of linguistics, political science, and communication, this book provides a broad perspective on how language is intertwined with our sense of belonging.
