According to David Bradley (2004), Naluo (Naruo, Laluo, Naru, Shuitian 水田, Shui Yi 水彝 (used in Yunnan)) is spoken by about 15,000 people mostly in eastern Yongsheng County and southern Huaping County, Yunnan, as well as in Pingjiang 平江 and Futian 福田镇 townships, western Panzhihua City, Sichuan. Naluo is moribund or extinct in Sichuan, and endangered in Yunnan.
