The Sani people, a branch of the Yi ethnic group, are distributed in Shilin County, Yunnan Province. They are hardworking, kind and lively. Don't think that the names of the Sani people and the Samei people are only one character different, and their clothes will be very similar. In fact, the clothes of the Sani people and the Samei people are completely different. The famous film "Ashima" is adapted from the famous folk poem of the Sani people of the Yi ethnic group. The film attracted thousands of people to Shilin, the hometown of Ashima. The clothes of Ashima and Aheige in the film are the clothes of the Sani people of the Yi ethnic group. The clothes of the Sani people are quite distinctive among the Yi people. Sani men wear a double-breasted sleeveless short jacket made of linen, embroidered with patterned patterns, and decorated with blue or other colored cloth edges. Wearing it, they look generous, simple and healthy. Sani women wear colorful flower hats on their heads. This flower hat is made of strips of various colors. A pair of triangular embroidered corners are inserted at the top perpendicular to the ears. When a girl has a loved one, she will take them off and give them to him as a token of love. The upper and lower ends of the hat brim are decorated with silver bubbles, white beads or shells. Several strings of small beads are tied to the ears and hung down to the chest. When walking, they make a tinkling sound, attracting people's attention. The top of Sani women is a high-necked long gown with a right opening, and the collar and cuffs are bordered with colorful cloth or exquisite embroidery. A red or black apron is tied around the waist, and various colorful patterns are embroidered on the apron. They wear blue, white, and black trousers with ribbon borders and embroidered cloth shoes. Such clothing sets off the Sani girls. In the beautiful Shilin, the clothing of the Sani people adds a strong national color to it. The hardworking and wise Sani women have cultivated and developed their ambiguous nature and exquisite hand-sewing skills in the cultivation of beautiful mountains and rivers. Their clothing is exquisitely crafted, colorful, generous, and bright. A piece of clothing is a fine work of art. The picturesque landscape is an important part of the historical and cultural background of the Yi Township. From the colorful patterns of clothing, we can see the shadows of blue sky and white clouds, exotic flowers and rocks, and the integration of natural landscape and cultural landscape, which has cultivated the aesthetic concept and noble sentiment of the Yi people. Clothing is not only used to keep warm, it is indeed a flower of national culture that never fades.
