Men wore 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.
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.
Dai festivals, closely related to religious activities, included the "Door-Closing" festival in mid-June by the lunar calendar, the "Door-Opening" festival in mid-September, and the "Water-Splashing" festival in spring. "Door-Closing" started three months of intensive religious activities. "Door-Opening" marked the beginning of normal life. "Water-Splashing," still held every year, is the most important festival. Before the festival, pigs and chickens are slaughtered and wines are brewed with other festival foods also being prepared beforehand. During the three days of the festival, rich and colorful activities are held. Dragon boat racing and other performances such as Peacock dance are held on the first day followed by the characteristic water- splashing even on second day. The last day is usually for young people to play games as a way of expressing their love for each other. Usually held by the banks of River, girls of Dai ethnic minority dip branches into the river and sprinkle the water onto others as a way to express their best wishes at the beginning. The climax of the water-splashing activity is when the people of the different ethnic groups attending the festival splash water upon each other, using basins and buckets. Although all the people are soaked to the skin, all participants are happy.
