Help me introduce the origin and history of the Dai people.

Dai population is 6.5438+0.25 million. Dai people mainly live in Xishuangbanna Dai Autonomous Prefecture, Yunnan, and the rest are distributed in counties and cities in Yunnan. Dai people call themselves "Dai" and "Dai Ya", later called Dai. Dai language belongs to the Zhuang-Dong language family of Sino-Tibetan language family, and it is a traditional phonography. Dai people believe in Hinayana Buddhism. The Dai people have a long history, and there are records about the ancestors of the Dai people in the history books of China in 1 century BC. In 109 BC, Emperor Wu of the Han Dynasty established Yizhou County, and the Dai area was under the jurisdiction of Yizhou County. In 69 AD, the Dai area belonged to Yongchang County. During the Ming and Qing dynasties, the policy of abolishing hereditary chieftain and replacing it with temporary officials (that is, floating officials) was implemented in minority areas, and the Dai areas gradually came under the direct rule of the court. During the Republic of China, counties and bureaus were established in Dai areas. The bamboo building where Dai people live is a dry-column building. The bamboo building is approximately square, supported by dozens of large bamboos, and the floor is suspended; The roof is covered with thatched rows, and the bamboo wall has a large gap, which is both ventilated and light-permeable. The slope on both sides of the roof is very large, showing an A-shape. The bamboo building is divided into two floors, where people live upstairs, livestock are raised downstairs and sundries are piled up. It's also a place for rice and weaving. Dai men usually wear collarless double-breasted shirts and long-sleeved trousers wrapped in white or blue cloth. Dai women's clothing varies from place to place, but it is basically characterized by bunches of hair, skirts and shirts. The skirt is ankle-high, the clothes are tight and short, the hem only reaches the waist, but the sleeves are long and narrow. The Dai people take rice as their staple food, and the most distinctive one is bamboo tube rice. The production method is to put rice in a fresh bamboo tube, add water, and barbecue on the fire, which is fragrant and delicious. Pu 'er tea, a specialty of Xishuangbanna, Yunnan Province, was exported to all parts of China in the Tang Dynasty and Southeast Asia and South Asia in the Qing Dynasty. Now it has entered the markets of Japan, Western Europe and other countries and regions and become a famous tea at home and abroad. Dai people have their own unique calendar. The difference between Dai calendar and Gregorian calendar is 638 years, that is, Gregorian calendar is 639 years as the first year of Dai calendar. The year of Dai calendar is solar year, but the month is lunar month. Dai calendar is divided into three seasons, from 1 month to April as the cold season, from May to August as the hot season, and from September to1February as the rainy season. Dai people love poetry very much, especially long narrative poems. Narrative poems such as Zhao Shuli, Nan Manna, He E and luo sang are valuable cultural heritage of the Chinese nation. There are many kinds of Dai dances, and their movements and contents mainly imitate the activities of local common animals, and on this basis, they are personalized. Peacock dance not only comes from imitating the graceful movements of peacocks, but also from the beautiful and moving legends of Dai people. The famous dancer Dao Meilan is famous at home and abroad for her performance in peacock dance. Songkran Festival is the most national festival of Dai people. Songkran Festival is the New Year of Dai calendar, which lasts from June 6th to July 6th, equivalent to April in Gregorian calendar. At the Water-Splashing Festival, people will worship Buddha. The girls will wash the dust for the Buddha with fresh water floating with flowers, then splash water on each other and bless each other. At first, water was splashed with hands and bowls, and then songs were splashed with pots and barrels. The more intense the splashing, the drums, gongs, water splashing and cheers became one.
