Chinese and English are both official languages. Chinese, especially Cantonese in the spoken form, is the common language, however, and is almost universally understood. A variety of dialects and other languages are used among the ethnic minorities. Apart from Cantonese, common dialects such as Teochew, Hakka, and Tanka are used within separate communities of the Guangdong and Hong Kong Chinese. Groups from other parts of China are also likely to use their own native dialects, and, similarly, the non-Chinese are likely to use their own native languages among themselves. The use of Mandarin Chinese has risen as Hong Kong has reintegrated with China. Britannica
