The Dai language belongs to the Chinese-Tibetan language family and has three major dialects. It is written in an alphabetic script.
Customs and Habits
The marriage of the Dais was characterized by intermarriage on strictly equal social and economic status. Pre-marital social contact between young men and women was quite free, especially during festivals. It was common for the groom to move into the bride's home after the wedding.
The graveyards of aristocrats and poor people were strictly separated. When a monk or a Buddhist leader died, he was cremated and his ashes placed in a pottery urn to be buried behind a temple.
The Dai costumes are simple and elegant. Men wear collarless tight-sleeved short jackets, with the opening at the front or along the right side, and long baggy trousers. In winter they drape a blanket over their shoulders. They wore black or white turbans. Tattooing was common. When a boy reached the age of 11 or 12, a tattoo artist was invited to tattoo his body and limbs with designs of animals, flowers, geometric patterns or the Dai written script. Traditionally, women wore tight-sleeved short dresses and sarongs.
Rice is the staple food. The Dais in Dehong prefer dry rice, while those in Xishuangbanna like sticky rice. All love sour and hot flavors. In addition to beef, chicken and duck, they enjoy fish and shrimp. Cabbages, carrots, bamboo shoots and beans are among the popular vegetables. The Dais also love wine, liquor, and betel nuts.
The villages of the Dais are found on the plains, near rivers or streams, and among clusters of bamboo. The buildings generally are built on stilts. Some of the houses are square, with two stories. The upper story serves as the living place, while the lower space, without walls, is used as a storehouse and for keeping livestock.
The Dai celebrate many festivals, the most important of which is the "Water-Splashing" festival, during which the Dais splash water on one another, and hold dragon boat races in the hope of chasing away all the illnesses and bad fortune of the past year and bringing about good weather and bumper harvests.
The Dais have a rich, colorful culture. They have their own calendar, which started in 638 A.D. There are books in Dai script for calculating solar and lunar eclipses. Dai historical documents carry a rich variety of literary works covering poetry, legends, stories, fables and children's tales. They love to sing and dance, accompanied by their native musical instruments.
