I want to know the answer to the following question:
What language do the Yi people speak?
All the background I'm provided with is that "The Yi people of Liangshan Yi Autonomous Prefecture in southern Sichuan speak the Nuosu language, which is one of the Lolo-Burmese languages; Yi is written using the Yi script, a syllabary standardized in 1974.". Is that enough to answer the question?
Answer: yes
