Changzhou random needle embroidery is an important school of Suzhou embroidery, also known as "regular embroidery" and "brocade embroidery". It originated in Changzhou for more than a hundred years and spread throughout Jiangsu. This project is a traditional art in the fifth batch of national intangible cultural heritage representative project list. Changzhou people have a long history of planting mulberry and hemp and producing silk. In the late Qing Dynasty and early Republic of China, embroidery vocational schools and embroidery specialty shops emerged in Changzhou. Mr. Yang Shouyu, the founder of Changzhou random needle embroidery, changed the traditional flat needle embroidery technique of "parallel needles and close thread connection" and took the concept of sketching and oil painting as a guide. He used needles to draw and threads to express ideas, and innovated into a criss-cross and long and short embroidery method, which is called "random needle embroidery". A complete Changzhou random needle embroidery work must go through many complicated and strict processes such as designing composition, selecting base material, sparse needles to lay the base, dense needles to make fine, adding color and modeling before it can be completed. The biggest characteristics of Changzhou random needle embroidery are two points. One is that the needle technique is flexible and changeable. There are large random needles, small random needles, oblique random needles, pulled needles, vertical cross needles and other needle techniques. The changes in length, thickness, direction and angle are extremely different from traditional embroidery; secondly, the color laying is clearly layered. Each work is divided into a basic layer, a performance layer, a balance layer, etc., and each layer is completed with mixed color threads. As a representative of this project, Mr. Yang Shouyu created works such as "Old Man's Head" and "Girl and Swan", which once caused a sensation in the Chinese embroidery and painting circles. His representative work "Roosevelt" was presented to the US President as a state gift. After a hundred years of inheritance, this project has emerged as a group of representative inheritors with their own merits, including Chen Yaxian, Pan Xiqin, Sun Yanyun, Di Jing, Shan Yindi, and Zhou Mingmin. Su embroidery (Changzhou random needle embroidery) contains rich cultural and historical information, and has multiple values such as humanities, aesthetics, and practicality. It is a representative art form of Chinese traditional culture. (No pictures yet, welcome to provide.) (No pictures yet, welcome to provide.)
