It looks like Nuosu and Loloish are different ways of referring to the same language (group) with Lolo being the Chinese name and Nuosu being their name for themselves. https://en.wikipedia.org/wiki/Nuosu_language https://en.wikipedia.org/wiki/Nuosu_language > Nuosu is one of several often mutually unintelligible varieties known as Yi, Lolo, Moso, or Noso; the six Yi languages recognized by the Chinese government hold only 25% to 50% of their vocabulary in common. They share a common traditional writing system, though this is used for shamanism rather than daily accounting. I bow to your superior expertise when it comes to the differences between Sichuanese and Mandarin but all of Sìchuān is definitely part of the Mandarin speaking area. The book to buy if you’re interested in this is the Language Atlas of China. https://en.wikipedia.org/wiki/Language_Atlas_of_China https://en.wikipedia.org/wiki/Language_Atlas_of_China
