The two varieties, Biao Min and Jiaogong Mian, are evidently not mutually intelligible.
Ethnologue reports the Biao Min language to be spoken in the following counties in China.
Strecker (1987) uses "Chao Kong Meng" for Shikou, and "Moxi" for Niuweizhai.
[5] Word lists for Biao Min dialects can be found in Mao Zongwu (2004).
[8] The Jiangtang and Baizhuping dialects of Biao Min are documented in Hsiu (2017).
