Among them, Yushuiping Site (Tongdian Town, Lanping County, Nujiang Prefecture) has been identified for at least 10,000 years, and Tangzigou Site (Pupiao Town, Longyang District, Baoshan City) has been identified for at least 8,000 years. From the unearthed relics of houses, fire, farm tools and animal fossils, we can see the wordless history books of Dai ancestors, which are rich in information, heavy and vivid.
At least 3,000 years ago, Dai ancestors had established several small countries in the upper and middle reaches of Lancang River and Nujiang River, among which "Alina Zhang" was the most powerful. Sima Qian, a historian of Han Dynasty, recorded "Meng Zhang" as "a country riding elephants" in Historical Records.
In the 5th century BC, the small Dai countries in the middle and upper reaches of Lancang River and Nujiang River formed an alliance centered on "Meng Zhang", and King Meng Zhang became the co-owner of the whole alliance. People all over the world call it Zhaolong, kings all over the world call it Ailong, and Meng Zhang is gradually called Meng Daguang.
The records of Huayang Country, the Book of the Later Han Dynasty and other Chinese classics record this Dai allied country as "Ailao Country", while the Dai classics record it as "Meng Daguang Country" (transliteration of "Daguang Country", free translation of "Central Country").
In 109 BC, after the Han Dynasty annexed the Dian Kingdom (Dianchi Lake and Fuxian Lake), it conquered the Kun and Zhang tribes in the west of the Dian Kingdom, entered the territory of Meng Daguang (Ailao Kingdom) in the west, and set up military strongholds (counties).
Over the next hundred years, the nationalities such as Dian, Kun and Zhang turned against the Han Dynasty many times, and all of them were chased into Meng Daguang by the Han Dynasty. Dai ancestors absorbed a large number of nationalities such as Yunnan, Kun and Zhang, and finally formed a powerful nation.

Dai people's diet culture;
Most Dai people have the habit of eating two meals at a time, with rice and glutinous rice as their staple food. Dehong Dai's staple food is japonica rice, and Xishuangbanna Dai's staple food is glutinous rice. Usually eaten immediately. People think that japonica rice and glutinous rice will lose their original color and fragrance only if they are eaten immediately, so they don't eat overnight meals or seldom eat them, and they are used to kneading rice with their hands.
The Dai people live in a place with a low altitude and a wide area (commonly known as "bazi"). Due to the influence of natural factors such as climate and temperature, the most striking feature of the Dai people living on the dam is that they like to eat sour food, so they are called "acid".
In the famous dishes of the Dai nationality, almost all famous dishes are inseparable from acid. As a condiment, "acid" is both botanical, such as bamboo shoots and limes; There are animals, such as acid ants; There are also chemical reactions, such as vinegar (homemade).
On the one hand, the diet of Dai people is acidophilic, which is related to their living area. Dai people live in hot and dry places. Acidic food can not only help digestion, but also stimulate appetite and prevent heatstroke.
The Dai people's love for acid is gradually formed and preserved in the process of fighting against nature and overcoming natural factors such as high temperature. It is the simplest, most direct and most effective custom formed in the process of labor, and it is also the most eye-catching highlight in Dai food culture, which can best reflect the national characteristics.
