Chaoshan dialect is the prevailing dialect in the Chaoshan area, including Shantou, Chaozhou and Jieyang. The dialect spoken by Shantou residents is called Shantou dialect. Chaozhou dialect is a branch of Minnan dialect, which bears great differences from modern Chinese. It not only retains a lot of phonemes, tones, vocabularies and grammatical features of ancient Chinese and many substratum words of ancient Taiwan dialect, but also borrows words from Malaysian and English. Some Hakkas in Shantou also speak Hakka dialect.
