Dulong people have their own language, but no writing. In the past, we recorded and transmitted information by carving wood and knotting ropes. Dulong language belongs to the Tibetan-Burmese language family of Sino-Tibetan language family, which is basically the same as Gongshan Nu language.
Dulong people have lived in mountainous areas since ancient times, with harsh conditions and blocked traffic, so the social development is relatively slow and the productivity level is low. Before and after the founding of New China, there were still strong remnants of the primitive commune system. The economy is dominated by slash-and-burn extensive agriculture, and gathering and hunting also occupy a considerable proportion.
In Dulong language, "door rent" is a general term for various folk tunes, and "door rent wow" is a title for singers. Dulong people often use dancing and singing to express their feelings and events, such as production, harvest, hunting, building houses and weddings. Folk songs are simple in tune, free in rhythm and unique in style. Many fairy tales are handed down from generation to generation through "door rent". Women also have the habit of writing. Houses are mostly wooden houses or bamboo houses. The only festival is China New Year. In the past, there was no fixed time, and most of them were held in the twelfth lunar month, with different festivals. Dulong region borders Chayu County, Xizang Autonomous Region in the north, Gaoligong Snow Mountain at an altitude of 5,000m in the east and Myanmar in the southwest. The winding Dulong River roared in the mountains. In winter, the mountains are closed by heavy snow, and in summer, it is rainy and humid. Due to the influence of north-south topography and tropical monsoon in Indian Ocean, local plant growth and climate change have obvious vertical distribution characteristics.
