Hokkien /hɒˈkiɛn/ (traditional Chinese: 福建話; simplified Chinese: 福建话; pinyin: Fújiànhuà; Pe̍h-ōe-jī: Hok-kiàn oē) or Quanzhang (Quanzhou–Zhangzhou / Chinchew–Changchew; BP: Zuánziū–Ziāngziū) is a group of mutually intelligible Min Nan Chinese dialects spoken throughout Southeast Asia, Taiwan, and by many other overseas Chinese. Hokkien originated from a dialect in southern Fujian. It is closely related to the Teochew, though mutual comprehension is difficult, and is somewhat more distantly related to Hainanese. Besides Hokkien, there are also other Min and Hakka dialects in Fujian province, most of which are not mutually intelligible with Hokkien.
