The Dulong people are distributed in Gongshan Dulong and Nu Autonomous County of Nujiang Lisu Autonomous Prefecture. They were historically known as "Qiu", "Qiu Ba", "Luo", "Quluo", etc. They call themselves "Dulong" or "Dulong Achang". After the founding of New China, they were named Dulong. The Dulong language belongs to the Tibeto-Burman language family of the Sino-Tibetan language family, and the language branch is undetermined. There are two dialects of Dulong language, one is the Dulong dialect of Dulong River, and the other is the Nujiang dialect of the Nu Dulong language in Bingzhongluo, Nujiang. There are certain differences between these two dialects, but they can communicate with each other. The Dulong people had no written language in history. They recorded things and transmitted information by carving wood and tying ropes. In the early 1950s, Baiji Dutiqiku, a Burmese Riwang person, and Morse, a foreign missionary, created a Latin phonetic script with the spoken language of the Riwang clan as the phonetic characteristics, named "Riwang script". In the early 1980s, under the leadership of the local government, the Yunnan Provincial Committee for the Guidance of Minority Languages sent Mr. Long Chengyun to assist Mulimen John, a Dulong cadre of the Gongshan Cultural Center, to create the Dulong script. Based on the Riwang script, they drafted a set of Dulong phonetic schemes based on the actual situation of the Dulong language and the Dulongjiang dialect. In December 1983, the scheme was discussed and passed at the second plenary (enlarged) meeting of the Provincial Committee for Minority Languages held in Kunming and began to be implemented on a trial basis. The Dulong script has 45 initials, including 20 single consonant initials, 11 compound consonant initials, 6 palatalized consonant initials, 8 rounded consonant initials and 1 consonant coda; there are 72 finals, including 6 single vowels, 5 compound vowel initials, and 61 finals with consonant codas. Since the trial promotion of the Dulong language phonetic system in the early 1980s, it has been widely welcomed by Dulong cadres and masses, and is mainly used on both sides of the Dulong River and for communication and exchange among the people of Xiaocha La (a small part) in Bingzhongluo. However, since Gongshan is a poor county and there is a serious lack of funds, the promotion of Dulong language has been greatly restricted and has not been widely promoted among the masses.
