Hakkanese, also known as Hakka, Hakka, Hakka, etc., is also known as Ya dialect, Xinmin dialect, Tucantonese, Yuedong dialect, etc. It is a kind of tonal language in the Chinese family of Sino-Tibetan language family, and was defined as a language by UNESCO in 2009. Linguists still have some arguments about whether Hakka should be classified as a dialect or as a language, and it is considered as one of the seven major dialects of Chinese in China. Hakka language areas are mainly concentrated in the Hakka areas of Jiangxi, Fujian and Guangdong at the junction of eastern Guangdong, western Fujian and southern Jiangxi, and are widely used in southern China, Taiwan Province, Malaysia and some Chinese communities. It is generally believed that Hakka was initially shaped in the Southern Song Dynasty, but it was only in the 20th century that it was named Hakka. Hakka is represented by Meixian dialect.
