What is the traditional culture of the Dai people?

Also known as "Dai-Tai nationality" or "Tai-Lao nationality". Dai-Tai nationality originated from Yunnan-Guizhou Plateau in China, and established political power in Yunnan-Guizhou Plateau many times. After that, due to the oppression of the Central Plains Dynasty and other ethnic groups, they gradually migrated to Indochina Peninsula and South Asia subcontinent, distributed in Thailand, Laos, Myanmar, Viet Nam, Cambodia, India, China and other countries, with a total population of about 66 million, and China was about 654.38+0.26 million. No matter where you are, you can communicate simply in dialect. There are seven languages, including Siam, Lancang, Lanna, Terminal, Tense, Nizi and Ahong, which are all evolved from Indian Sanskrit letters. They are all written from left to right, with line breaks from top to bottom, but there are differences in form and structure. Dai people generally believe in Southern Buddhism, but in some areas Dai people believe in primitive religion and Hinduism. Most Dai people have the habit of eating two meals at a time, with rice and glutinous rice as their staple food. Many festivals are related to Buddhist activities. Menghai and other places still retain the custom of slaughtering sacrifices in the Songkran Festival (Songkran Festival). In the western version of a tribal god, some sacrifices must be black cows and white pigs. The Dai people in Yuanjiang and New Equality generally worship dragon trees and dragons. When the Dai people in Yuanjiang sacrifice the dragon tree in the third month of the lunar calendar every year, the whole village will slaughter the red bull. Before slaughter, it will be covered with white ash and covered with red and green cloth. In the same month, in order to protect the safety of livestock, pigs will be sacrificed to Heaven and Earth. Among the Dai people, especially in some remote areas, there are still some taboos in cooking, such as: burning firewood from the roots first; Don't cross the fire pit; You can't just move a tripod or something on the fireplace.
