On April 3, 2013, I interviewed Wang Dechang 王得昌 (male; date of birth: December 3, 1952) of Gusu village 古苏村, Kunzhai Township 昆寨乡, Nayong County, Guizhou, China who spoke a Loloish language called Nusuphu (autonym: [nɯ55 su21 phu33]). All Yi people in the township were "Nusuphu." He has also heard of the Caijia, but reports that there are now completely Sinicized, with no ethnic language or customs remaining.
