Su embroidery (Yangzhou embroidery) is a traditional art project in the fourth batch of national intangible cultural heritage representative project list. It originated in the Han Dynasty, flourished in the Tang Dynasty, refined in the Song Dynasty, and flourished in the Ming and Qing Dynasties. It is located in the central part of Jiangsu Province, so there is a saying that "Guangling women are good at embroidery". Yangzhou embroidery includes many processes such as designing embroidery drafts, stretching and matching threads, embroidery, and mounting. The formation of the embroidery base is a necessary modification of the original painting, redrawing the draft that adapts to the characteristics of embroidery, and guiding the embroiderer to understand the painting. There are many kinds of embroidery needles, including neat needles, loose needles, spiral needles, connecting needles, rolling needles, and floating needles. There are many things to pay attention to when choosing needles. The starting and ending needles are "flat, even, neat, and dense"; the lines are arranged with proper density; the skins are overlapped, and the needles are embedded; the inlay colors are harmonious and the silk texture is natural. Yangzhou embroidery is dominated by ink embroidery, with a special style and distinct personality, using needles instead of pens and threads instead of ink. It integrates the principles of painting and embroidery, with a free and easy style, mellow charm, and full of ink and wash. Its soul and essence are to express the painter's brush and ink skills through needlework to reflect the artistic conception, charm, and momentum of traditional Chinese painting, so that it is difficult to distinguish between embroidery and painting. Yangzhou embroidery is known for its fine splitting, meticulous needlework, rich colors, and fresh and elegant style. It combines talent and perception, the so-called "heart-line magic needle", thus forming a unique artistic style of "precision, elegance, harmony, smoothness, uniformity, liveliness, transparency, and cleanliness". Yangzhou embroidery is perfectly combined with the Yangzhou School of Painting, showing the thickness and refinement of Yangzhou culture. Representative works include "Sending Charcoal in the Snow", "Spring Flowers on the Sea", "Traveling Picture", "Double Fish Picture", "Grass Chrysanthemum Picture", "Nine Knowledge Picture" and other Yangzhou embroidery works from different periods, reflecting people's aesthetic concepts and value orientations as well as folk customs in a specific period. Yangzhou embroidery is mainly passed down through family inheritance and master-apprentice teaching. Now that the existing old artists and apprentices have gradually reached retirement age, embroidery is facing the embarrassing situation of no successors. Its inheritance and protection work hopes to receive help and support from the government and all sectors of society. (No pictures yet, welcome to provide.) (No pictures yet, welcome to provide.)
