Longjia (autonym: suŋ55 ni55 mpau21) is a Sino-Tibetan language of Guizhou, China related to Caijia and Luren.
The Puding County Almanac (1999) reports that the Longjia language (autonym: Songnibao 松泥保) has 38 onsets and 22 rimes (8 simple, 14 complex).
[1] Their language is known as Nanjinghua (南京话; "Nanjing speech"), which is probably now functionally extinct.
[12] In Jianxinhe village 建新河村, Kunzhai Township 昆寨乡, Nayong County, Guizhou Province, the phrase suo55 mu33 ‘eat rice’ was elicited from an elderly rememberer of Nanjinghua.
[12] As suo55 is derived from Proto-Tibeto-Burman *dzya ‘to eat’, this points to Nanjinghua having an SVO word order like Caijia, Longjia, Bai, and Sinitic languages.
