Choyo language

Queyu (Choyo, Choyu) is a Qiangic language of Yajiang County and Xinlong County, Sichuan. It is similar with and shares a name with Zhaba, but the two languages are distinct from each other.

Dialects
The four dialects of Choyo are those of:
 * Youlaxi Township 尤拉西乡, Xinlong County (Wang 1991; Huang ed. 1992) (which also has Western Horpa speakers )
 * Rongba Township 绒坝乡, Litang County (Nishida 2008)
 * Tuanjie Township 团结乡, Yajiang County (Lu 1985; Sun ed. 1991)
 * Xiala Township 呷拉乡, Yajiang County (Prins & Nagano 2013) (which also has Dao speakers )

Suzuki & Wangmo (2016) consider the Lhagang Choyu language to be similar to but not part of Choyu proper, which consists of the four dialects listed above.

Huang & Dai (1992) document the Queyu dialect spoken in Youlaxi Township 尤拉西乡, Xinlong County, Ganzi Prefecture, Sichuan.

It used to be spoken in Xiya 西雅 Hamlet of the same township (Suzuki & Wangmo 2016:63). Lhagang Choyu is an endangered language with about 100 speakers.
