Micro embroidery is a traditional handicraft of Han nationality in Wuxi, Jiangsu. Wuxi is located in the south of the Yangtze River and is rich in silk. Wuxi embroidery is called "tin embroidery" for short, and it has a history of more than 2000 years. Especially in the Ming and Qing Dynasties, tin embroidery was widely spread in Shengxing as a Han folk craft and family sideline. In the long-term historical development process, it has created colorful stitches and accumulated many excellent traditional skills. The first Nanyang persuasion conference won the gold medal. Since liberation, especially since 198 1, we have studied "tin embroidery" and created "subtle embroidery" on the basis of inheriting the traditional stitch method. The artistic features of implicit embroidery are mainly manifested in its small size, ingenious conception and exquisite embroidery skills. Today, tin embroidery, like painting, represents a historical inheritance skill, and protecting it is to preserve a mark of human history.
