Huiyang Danshui Town is an ancient town with a long history. According to legend, it was a small market called "Shang Market" at the end of Song Dynasty, which was later renamed as "Guodu Town". In order to guard the coastal areas, the Ming Dynasty established the Freshwater Acropolis and protected the coastal areas of Daya Bay. With the development of economy, the growth of population and the convenience of land and water transportation, in the early Qianlong period of Qing Dynasty, it had become a large market town, changed into a fresh water market, and set up administrative institutions such as "Division". After the Opium War, this place became the import and export place of Huiyang and Hong Kong, and the commercial trade developed rapidly, forming such specialized commodity trading streets as "Big Fish Street", "Pig Street", "Lantern Street" and "Rice Street".
Danshui Town has always been a place where Hakkas live and live in history. At the end of Ming Dynasty and the beginning of Qing Dynasty, some Hakkas living in Meizhou moved east, south and west, and some Hakkas moved to Huiyang and Huidong. At this time, the Hakka people who moved to Huiyang and Huidong spoke Meizhou Hakka dialect with Meicheng accent in Meizhou city (Meijiang District and Meixian District) for generations. For hundreds of years, Hakka dialect has influenced the surrounding dialects with its own advantages, and it is also inevitably influenced by the surrounding dialects, especially Cantonese. By accepting some factors of these dialects, Huiyang Hakka dialect, which is slightly different from Meizhou dialect, has gradually formed.
