Native speakers refer to the language as Gangjdoj, which means "local language".
André-Georges Haudricourt in 1956 included the language of Tianzhou, the county seat of Tianyang, under Dioi, his name for Northern Zhuang.[2]
Based on data from the 1950s Guangxi Zhuang language survey, Tiandong, Tianyang and a suburb of Baise City were grouped together. This grouping was sometimes called Tianyangese (田阳音系). In the 1999 A Study of Zhuang Dialects this group was referred to as the Youjiang language (右江土语),[3] and in 2007 Youjiang Zhuang was added as a separate language to Ethnologue.[1]
Phonology
Youjiang Zhuang has 10 tones, and can be considered as having 20 initials and 83 finals, though some speakers pronounce the initials /ʔb/ and /ʔd/ as /m/ and /n/ respectively.[4]
