'Chinese' Is a Single Language

Chinese is a language family, not a unified language. Mandarin, Cantonese, Hokkien, Shanghainese, and others are mutually unintelligible to native speakers, a speaker of Cantonese cannot spontaneously understand Mandarin, and vice versa. By linguistic standards, mutual intelligibility determines whether speech varieties are dialects or separate languages. These varieties were historically called 'dialects' due to political factors: China's written language is standardized as Han characters, and the Communist government promoted Mandarin as a lingua franca. Linguistically, however, calling Cantonese a 'dialect of Chinese' is equivalent to calling Portuguese a 'dialect of Spanish' because they share historical roots. The shared writing system masks profound linguistic differences in phonology, grammar, and vocabulary that would classify these as distinct languages if they lacked unifying cultural and political frameworks.
