On August 25, 2012, in Tianba, Dongdu Village, Tiechang Township, Malipo County, Yunnan, China, I interviewed a 78-year-old man named Yang Guangsheng 杨光升, whom I recorded some White Gelao words from. Yang spoke White Gelao quite fluently. He reported other White Gelao speakers as (1) Yang Guangpu 杨光甫, a White Gelao speaker in Fengyan, and (2) Yang Guangqing 杨光睛, a White Gelao speaker of Fanpo, Yangwan Township who is the brother of Yang Guangsheng 杨光升.
