Huizhou (Chinese: 徽州话), or the Hui dialect (Chinese: 徽语), is a group of Sinitic languages spoken in and around the historical region of Huizhou (for which it is named), in about ten or so mountainous counties in southern Anhui, plus a few more in neighbouring Zhejiang and Jiangxi.
Although the Hui area is small compared with other Chinese dialect groups, it displays a very high degree of internal variation, and the lect is also situated near many mutually unintelligible varieties, making its classification difficult. It has been previously grouped with Huai, Wu, and Gan, and some even believe that it does not even constitute a singular language family.
