Hokkien or Quanzhou–Zhangzhou (Chinchew-Changchew; BP: ) is a group of mutually intelligible Min Nan Chinese dialects spoken by many overseas Chinese throughout Southeast Asia. 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. The Amoy and Taiwanese prestige dialect (based on Tainan variant) are considered standards. To clarify, besides Hokkien, there are also other dialects in Fujian province.
