In general, Quanzhou accent is more common along the coastal region and is known as the "hái-kháu" accent; Zhangzhou accent is more common within the mountainous region of Taiwan and is known as the "lāi-po͘" accent. The regional variation within Taiwanese may be attributed to variations in the mixture of Quanzhou and Zhangzhou accents and/or lexicons. It ranges from Lukang accent (based on Quanzhou accent) on one end, to the northern coastal Yilan accent (based on Zhangzhou accent) on another end. Tainan, Kaohsiung and Taitung accents, on the other hand, are closest to the prestige accent.
