Among many people, there is still a common misunderstanding that there is a single language known as Chinese. The two most prominent languages among Chinese people are Mandarin and Cantonese, each with distinct traits. Mandarin is the official language of both Taiwan and the People's Republic of China, together boasting over a billion speakers. Cantonese flourishes in the Guangdong region of China and in Hong Kong, as well as in some overseas Chinese communities. Its tonal system sets it apart from Mandarin.
