“Cantonese, a sharp, cackling dialect full of slang and exaggerated expressions, was never the dominant language of China. But it came to dominate the Chinatowns of North America because the first immigrants came from the Cantonese-speaking southern province of Guangdong, where China first opened its ports to foreigners centuries ago. But over the last three decades, waves of Mandarin-speaking mainland Chinese and Taiwanese immigrants have diluted the influence of both the Cantonese language and the pioneering Cantonese families who ran Chinatowns for years.”
