Hui is spoken over a small area compared to other Chinese varieties: 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. Despite its small size, Hui displays a very high degree of internal variation. Nearly every county has its own distinct dialect unintelligible to a speaker a few counties away. It is for this reason that bilingualism and multilingualism are common among speakers of Hui.
Huizhou Chinese was originally classified under Jianghuai Mandarin, but it is currently classified separately from Jianghuai. The Chinese Academy of Social Science supported the separation of the Huizhou Chinese from the Jianghuai Mandarin dialects in 1987.
In the Ming and Qing dynasties Jianghuai speakers moved into Hui dialect areas.
Some works of literature produced in Yangzhou, such as Qingfengzha, a novel, contain Jianghuai Mandarin. People in Yangzhou identified by the dialect they speak, locals spoke the dialect, as opposed to sojourners, who spoke dialects like Huizhou or Wu. This led to the formation of identity based on dialect. Large numbers of merchants from Huizhou lived in Yangzhou and effectively were responsible for keeping the town afloat. Merchants in the later imperial period also sponsored operas and performances in the Hui dialect. 
Hui can be divided into five dialects:
- Jixi-Shexian, spoken in Jixi, She County, Huizhou, Jingde, and Ningguo, Anhui province, as well as Chun'an, Zhejiang province
- Xiuning-Yixian, spoken in Tunxi, Taiping, Xiuning, Yi County, and Qimen, as well as Wuyuan, Jiangxi province
- Qimen-Dexing, spoken in Qimen and Dongzhi, Anhui province, as well as Fuliang, Dexing, and Wuyuan, Jiangxi province
- Yanzhou, spoken in Chun'an and Jiande, Zhejiang province
- Jingde-Zhanda, spoken in Jingde, Qimen, Shitai, Yi County, and Ningguo, Anhui province

Many dialects of Hui have diphthongs with a higher, lengthened first part. For example, 話 ("speech") is /uːɜ/ in Xiuning County (Putonghua /xuɑ/), 園 ("yard") is /yːɛ/ in Xiuning County (Putonghua /yɛn/); 結 ("knot") is /tɕiːaʔ/ in Yi County (Putonghua /tɕiɛ/), 約 ("agreement") is /iːuʔ/ in Yi County (Putonghua /yɛ/). A few areas take this to extremes. For example, Likou in Qimen County has /fũːmɛ̃/ for 飯 ("rice") (Putonghua /fan/), with the /m/ appearing directly as a result of the lengthened, nasalized /ũː/.

According to Hirata, however, Hui is composed of many layers: its dialects are spoken in an area originally occupied by the Yue i* tribe, suggestive of a possible substrate, later to be overlaid by migrations from Northern China in the Medieval Nanbeichao period and the Tang and Song dynasties. This was followed by the Jiang-Huai Mandarin dialects of the migrants who arrived during the Ming and Qing periods, and more recently by Wu dialects in particular, acquired by peripatetic Hui merchants who have represented an active

Some grammatical features of Yangzhou dialect are shared with Jianghuai Mandarin. Others may be of more limited usage but are used in Dingyuan County (the setting of Qingfengzha), which belongs to the same subgroup of Jianghuai.
