The Mongolian embroidery of Keyouzhong Banner originated in the Qing Dynasty. It has been integrated and influenced by the embroidery techniques of Han, Manchu, Tibetan and other ethnic groups. It often uses bold, rough, exaggerated techniques and bright colors to express the concept of harmonious coexistence between man and nature. There are 9 categories and more than 40 kinds of Mongolian embroidery needles in Keyouzhong Banner. The patterns are mostly taken from daily life and nature, such as flowers, plants, five domestic animals, birds, etc., as well as traditional auspicious patterns such as Huiwen and Yunwen. Different geometric forms are formed by points, lines, surfaces, squares, circles, curves and straight lines. The Mongolian embroidery works of Keyouzhong Banner are simple and fresh, with harmonious colors, exquisite patterns, and delicate and unique. They provide precious physical historical materials for the study of traditional ethnic calligraphy and painting pattern art, arts and crafts, clothing culture and Horqin folk customs.
