Beijing mending embroidery, commonly known as silk mending embroidery, was created for the needs of the court in history. It is a traditional handicraft that has been passed down from generation to generation and survives to this day. Beijing mending embroidery mainly uses various colors of cotton cloth, silk, and satin to cut into various designed patterns and shapes, carefully piled up to form a complete picture, and then embroidered with colored threads. The mending embroidery craft originated from the Liao and Jin Dynasties, was established in the Yuan Dynasty, and flourished in the Ming and Qing Dynasties. It is a combination and development of my country's ancient embroidery skills and the "pile silk" and "stick silk" skills of the Tang Dynasty. It uses natural plant fibers (cotton, linen, silk) as materials, and is a decorative art that combines a variety of techniques such as relief, weaving, embroidery, sewing, piling, and drawing. After the Liao and Jin Dynasties, the Beijing mending embroidery craft gradually moved from the folk to the court. Historically, the court set up special institutions to organize the production of embroidery in all dynasties. For example, the imperial palace and officials in the Liao Dynasty set up the "Yanjing Yuanshi", the Jin Dynasty set up the "Wenxiu Bureau", the Yuan Dynasty set up the "Wenxiu General Institute" and "Embroidery Bureau", and the Ming Dynasty set up the "Imperial Supervision". In the Qing Dynasty, the dyeing and weaving bureau of the Ministry of Internal Affairs had dyeing and clothing workshops. In the 33rd year of Emperor Guangxu's reign (1907), the Women's Embroidery Department of the Ministry of Industry and Commerce of the Capital was established to promote the art of mending embroidery. The concubines in the palace of the Qing Dynasty also liked mending embroidery, and they were sold outside the palace through eunuchs. The Qianlong period of the Qing Dynasty (1736-1795) was the most prosperous period for mending embroidery in Beijing. Whether officials or civilians, people liked mending clothes and clothing, and the amount of embroidery required each year was very large. In the Caoshi area outside Qianmen, there were official embroidery workshops that served the royal family and nobles. The processes of Beijing mending embroidery include pattern design, cutting, piling, embroidery, and coloring of individual patterns. Piling is the main method, and embroidery is supplemented. Mending embroidery is divided into two types: flat-cut mending embroidery and three-dimensional mending embroidery. The final formation of mending embroidery technology is mainly due to the rich weaving and embroidery techniques. On the basis of fabrics, the patchwork technique borrows and adopts a variety of techniques such as relief, weaving, embroidery, sewing, patching, and drawing. After a hundred years of development, its skills have broken the norms and limitations of traditional patchwork and patching, and created a variety of new techniques such as painting.
