Of the 1.3 billion residents of China, approximately 850 million speak Mandarin Chinese
as their first language. For more than 60 million others, Cantonese Chinese is their first
language. Although both languages are sometimes called "Chinese," the two sound so
different that Mandarin speaker and a Cantonese speaker cannot understand one
another. Mandarin, spoken in Beijing and much of northern China, is the official language
of mainland China. Cantonese, however, is more common in southern China and Hong
Kong. Both languages are tonal, meaning that when pronouncing words, the voice must
rise or fall in certain ways. However, Mandarin has four tones, while Cantonese has nine
different ones.
