On February 10, 2014 in U Nhí Chải, Dao San Township, Phong Tho District, Lai Chau Province, Vietnam, I collected a word list of U Nhi or Hani (ha³³ȵi³³pʰa⁵³). U Nhi turned out to be a local exonym for the Hani people in the area. My informant was a middle-aged woman about 50 years old who was more fluent in Southwestern Mandarin (which the locals called Hanhua 汉话) than in Vietnamese. The Hani language spoken in Phong Tho is similar to Hani dialects spoken in Jinping County, which is located just across the border. Three months later, I visited Jinping County but did not collect data on any languages there.https://sites.google.com/site/msealangs/sino-tibetan/hani-dao-sa
