Wen County, at the southern end of Gansu Province, is home to an ancient ethnic group with more than 5,800 people - the Baima people, descendants of the Di ethnic group. The Baima people have a unique language, special skin color, and different living styles from the Han people. Most experts and scholars call them the only "Chinese Baima people" in the country. The Baima ethnic group in Wen County has the surnames of Ban, Yu, Yang, Zhu and Cao. They are distributed in 10 natural villages including Meigong Mountain, Rugong Mountain and Qiangqu in Tielou Township, a place with deep mountain ravines and steep terrain. The Baima River cuts through the high mountains and turbulently flows through the territory. The Baima people built villages in the mountains on the river bank and engaged in agricultural production.

For more than two thousand years, the life of the Baima people has been based on agriculture, mostly eating corn, oats, buckwheat, potatoes, and mountain vegetables. Regardless of whether they are rich or poor, they all live in mud-walled houses. The Baima people call themselves "Dagabei" and their clothes are beautiful and interesting. The rich people's clothes are basically the same as those of the Han people, while the rest of the people wear colorful clothes and do not wear Chinese clothes. The man wears a "shaga" (a unique white felt hat) with golden pheasant feathers and white rooster feathers on it, white woven clothes and trousers, a belt around the waist, and leggings under the knees. Women usually wear long, tight-fitting robes with simple embroidery patterns on them. During festivals, they wear pleated skirts sewn with strips of various colors with complex and gorgeous patterns. They wear black sapas on their heads, braided with agate, and brown blouses with long sleeves. Colorful edging; silver-white fish bone pieces on the head and chest, a black apron around the waist, yellow, red, green, and orange colored belts swaying slightly in the wind, and earrings, bracelets, rings and other accessories that are shiny and strangely bright.

The Baima people oppose intermarriage with foreigners. They all abide by a custom that marriages are usually arranged by parents. What they worship most are the sun god, fire god, grain god, mountain god and other primitive gods. Each village has different mountain gods with different names. The Baima people are good at singing and dancing, and their singing and dancing are basically taught by word of mouth and example. The most solemn of their festivals is the Spring Festival. The content of the festival is unique, such as bonfire night, "Chi Ge Day" sacrifice, torch greeting, fire ring dance, sending off the god of plague, etc. On the second day of the first lunar month, relatives of the same surname are reunited, and then they take turns hosting banquets to enhance unity within the clan. On the 15th and 16th of the first lunar month, men, women and children dressed in festive costumes gathered in villages and villages. During the day, men put on sheepskin coats and masks and danced the "Twelve Phases", which is simple, majestic, and rugged. The women gathered in a group and sang beautiful love songs and toasts. At night, every family brings firewood and lights a bonfire. Men, women, old and young hold hands and form a large circle around the blazing fire. In the simple and cheerful white horse music, they dance the cheerful "fire ring dance" and "circle dance". "Round Dance" makes the whole village become a sea of ??joy in dancing and singing.
