Why do Chaoshan people in Guangdong speak Minnan?

Hui, Manchu and Mongolian people in Quanzhou will also use fluent Minnan language, and Hui people in Quanzhou who are not in Hui township will also use Minnan language.

Minnan dialect is regarded as a Chinese dialect by most linguists in China, and Minnan dialect is also one of the 10 languages recognized by UNESCO. According to different regions, it can be roughly divided into the following sub-dialects: Quanzhou Dialect, Zhangzhou Dialect, Xiamen Dialect, Chaozhou Dialect, Taiwan Province Dialect, South Zhejiang Min Dialect, Hailufeng Dialect, Huizhou Xuelao Dialect, Zhongshan Min Dialect, Leizhou Dialect, Dianbaili Dialect, Dianbaihai Dialect, Longyan Dialect, Ga Dialect, Penang Min Dialect in Malaysia and Singapore Min Dialect.

Chaozhou dialect, also known as Chaoshan dialect, is widely used in Chaoshan area of eastern Guangdong and overseas Chinese, belonging to a well-known branch of Fujian language family, which is quite different from Minnan dialect in Fujian and Taiwan Province. Grammar, like Fujian and Taiwan films, has a high degree of vocabulary correspondence, but there are obvious differences in pronunciation and intonation, which makes it difficult to communicate with each other. Chaoshan dialect contains many ancient Chinese elements, which originated from Minnan dialect (Putian dialect). At the end of the Southern Song Dynasty, hundreds of thousands of Putian people in southern Fujian migrated to today's Chaoshan area because they fled the war.
