Below are various names (both autonyms and exonyms) for speakers of Dai Zhuang (Johnson 2011a:43).

Johnson (2011b) splits Dai Zhuang into 4 dialects according to tonal splitting patterns: Northern, Central, Southern, and Northeastern. They roughly correspond with the following ethnic subdivisions (Johnson 2011a).

• Northern: Piled Headdress Tu (Da Tou Tu, 搭头土, Daigelai, Black Tulao). Spoken in northern Wenshan and western Yanshan counties.
• Central: Flat Headdress Tu (Ping Tou Tu, 平头土, River Bank Tulao). Spoken around the city of Wenshan, and in central Wenshan County's Panzhihua (攀枝花) Township.
• Southern: Pointed Headdress Tu (Jian Tou Tu, 尖头土). Spoken in Malipo and Maguan counties.
• Northeastern: Slanted Headdress Tu (Pian Tou Tu, 偏头土). Spoken in Guangnan and eastern Yanshan counties.

In Vietnam, Thu Lao (autonym: La Hừ, meaning 'black earth') is spoken in the following 7 villages (Nguyễn 2014:14).^[2]

• Mường Khương District, Lào Cai Province
  • Tả Gia Khâu Commune
    • La Hờ (48 households, 228 individuals)
    • La Măng (26 households, 123 individuals)
    • Lũng Thắng (15 households, 71 individuals)

Jerold Edmondson describes Thu Lao as a Central Tai language with about 200 speakers that retains voiced initial consonants in low tones, like Tay of Trùng Khánh District, Cao Bằng Province.^[3]

Yunnan (1979)^[4] reports that a Tai-speaking group called the Baiyi 摆彝 live in Wenshan City, Maguan County, and Qiaotou Township 桥头苗族壮族乡 of Hekou Yao Autonomous County. Yunnan (1979) suggests that it may be similar to Tai Lue. The Baiyi are classified as ethnic Dai in Hekou, and as Zhuang in Wenshan and Maguan. In 1960, the Baiyi had a population of 6,958.

Many Dai Zhuang dialects preserve voiced stops inherited from Proto-Tai (L-Thongkum 1997). L-Thongkum calls the dialects with the voiced stops "Dai Tho," and the dialects without any voiced stops "Tai Tho."
