Carpet weaving technique (Langzhong silk carpet weaving technique), a traditional technique of Langzhong City, Sichuan Province, is one of the national intangible cultural heritages. Silk carpet weaving technique is a traditional handicraft passed down from generation to generation by the people of Langzhong. Since the Ming Dynasty, silk carpet weaving workshops have appeared in Langzhong. In the middle of the Qing Dynasty, silk carpet weaving became the main livelihood of many families in towns. Before liberation, there were more than 10 famous family workshops in Langzhong, such as Zhang Family Flowers, Xue Family Landscapes, and Li Family Buddha Statue in Dafo Temple. Several generations of a family were engaged in silk carpet weaving. After accumulation, they formed their own different patterns and styles and passed them down from generation to generation. Langzhong hand-knotted silk carpets have been produced at a low output and expensive prices due to their exquisite raw materials and unique techniques. Buyers are limited to dignitaries from all over the country. Silk carpet weaving is divided into hanging warp, weft, bottoming, rake and manual flat carpet. The silk carpet weaving process is complicated and time-consuming. The number of silk threads per meter on the back of the carpet can reach more than 1,300, and the number of knotting points per square meter can reach 1 million. All the knotting and winding of the warp and weft are done by hand, with extremely high precision. A mature technician can only weave 3 to 4 square meters of silk carpets per year.
