Caijia () is an endangered Sino-Tibetan language spoken in an area centred on Bijie, in the west of the Chinese province of Guizhou. It was first documented by Chinese researchers in the 1980s. It has been described by different authors as a relative of Bai or an early split from Old Chinese. The autonym is . According to Lu (2022), Caijia speakers in Xingfa 兴发乡, Hezhang County refer to their language as .

Classification
Similarities among Old Chinese, Waxiang, Caijia, and Bai have been pointed out by Wu & Shen (2010) and others.
Zhengzhang Shangfang (2010) argued that Bai and Caijia formed a Greater Bai subgroup of Sino-Tibetan.

Caijia also appears to be related to the extinct Longjia and Luren languages, but they are too poorly documented for definitive classification.

In contrast, Sagart (2011) groups Caijia with Waxiang, a divergent Chinese variety spoken in northwestern Hunan, as the earliest group to split off from Old Chinese.
Sagart (2011) lists the following features of Old Chinese retained by both Caijia and Waxiang:
OC *lˤ- and *lr- > Caijia and Waxiang l- (where Middle Chinese has d-), as in OC *lˤiŋ () > Caijia , Waxiang  'field'
OC *r- > Caijia ɣ- and Waxiang z- (where Middle Chinese has l-), as in OC *mə.rˤək () > *rˤə > Caijia , Waxiang  'to come'
Sagart identifies two words as shared innovations:
'two': Caijia , Waxiang , from OC *tsˤə(ʔ)-s 'twice' ()
'milk': Caijia , Waxiang , which Sagart (2011) suggests is a non-Sinitic word

Distribution

Bijie (1983) reports the Caijia people are found in the seven counties of Bijie prefecture – Qixingguan, Dafang, Qianxi, Zhijin, Nayong, Weining, and Hezhang – comprising a total of over 3,100 households and over 18,000 individuals. Bijie (1983) reports that smaller populations of Caijia people are found in Anshun (with over 400 people) and Liupanshui (with over 3,500 people) prefectures (to the southeast and southwest respectively), as well as Zhaoyang, Yiliang, and Zhenxiong counties in Zhaotong prefecture, Yunnan (to the northwest). Bijie (1983) also contains linguistic data for the Caijia language of Hezhang County.

Caijia speakers are distributed in the following locations in Bijie prefecture (Bo Wenze 2004).

Lee (2021) also notes that vowels can have three additional forms: long , nasal , and r-colored . Although sources conflict, consonants can additionally be glottalized or pharyngealized, which of the two it is actually unclear. This is presumably marked with their respective IPA symbols.
