Due to the linguistic history of Hong Kong and Macau, and the use of Cantonese in many established overseas Chinese communities, the use of Cantonese is quite widespread compared to the presence of its speakers residing in China. Cantonese is the predominant Chinese variety spoken in Hong Kong and Macau. In these areas, public discourse takes place almost exclusively in Cantonese, making it the only variety of Chinese other than Mandarin to be used as an official language in the world. Because of their dominance in Chinese diaspora overseas, standard Cantonese and its dialect Taishanese are among the most common Chinese languages that one may encounter in the West.
