Mianzhu City is located on the northwest edge of the Sichuan Basin and is rich in bamboo. Mianzhu is the most famous bamboo, which is a good material for papermaking. The Mianzhu woodblock New Year painting technique is mainly distributed in Jiannan Town in the urban area of Mianzhu City and Gongxing Town, Qingdao Town, Xinshi Town, Xiaode Town and other places in the north. The middle section of Longmen Mountain in Mianzhu is connected to the northern part of Chengdu Plain. Chengdu has been the center of woodblock printing in China since the Tang Dynasty. Mianzhu was influenced by it. It is said that woodblock New Year paintings were produced in the Song Dynasty. According to oral data, during the Qianlong and Jiaqing periods of the Qing Dynasty, there were more than 900 New Year painting practitioners in Mianzhu, and more than 300 workshops of various sizes. The annual output of New Year paintings including door paintings, square paintings, screen halls, miscellaneous strips, rubbings, and cases was more than 12 million, which were sold to Yunnan, Guizhou, Shaanxi, Qinghai-Tibet, the two lakes and Sichuan Province. In addition to traditional door god paintings, the themes of Mianzhu woodblock New Year paintings also involve opera stories, landscapes, flowers and birds, landscape records, auspicious patterns, etc. There is a professional division of labor in the production of New Year paintings in various parts of Mianzhu. The urban area focuses on rubbings, miscellaneous strips, squares, and cases, and also includes door paintings; Qingdao Township focuses on colorful Qingshui robes; Zundao Township focuses on beauties and doll plays, and so on. When Mianzhu woodblock New Year paintings flourished, a guild organization "Fuxi Society" appeared to spontaneously evaluate New Year painting products. At the beginning of the 20th century, Mianzhu woodblock New Year paintings began to decline, and then became increasingly depressed, with many people closing down. Mianzhu woodblock New Year paintings are closely linked to local customs. There are many rules for posting them alone, which cannot be violated. The various images in the paintings also have different symbols and interpretations, and together with the images, they are reflected or presented in various folk rituals. In the Ming and Qing Dynasties, in addition to the 1 theme, a large number of opera themes appeared in Mianzhu woodblock New Year paintings. Mianzhu painters painted New Year paintings based on Sichuan opera repertoires, creating works such as "White Dog Fighting for Phoenix" and "Five Sons Telling Their Mother". In terms of genre, Mianzhu woodblock New Year paintings can be divided into "red goods" and "black goods". "Red goods" refers to painted New Year paintings, while "black goods" refers to woodblock rubbings printed with smoke ink or cinnabar. The production of Mianzhu woodblock New Year paintings includes drafting, engraving, printing ink, coloring, and covering flowers. Its artistic characteristics are: first, hand-painted, the same plate has different effects due to different hand-painted; second, symmetrical composition; third, the use of hue and chromaticity contrast, especially good at using gold (such as bitumen gold, piled gold, and pasted gold). But in comparison, the most distinctive feature is "filling water feet" (referring to a style of painting with residual pigment). After Qianlong in the Qing Dynasty, Mianzhu woodblock New Year paintings have produced famous masters and have never stopped. The main inheritors of this skill now include Li Fangfu, Chen Xingcai, etc. After the 1950s, Mianzhu woodblock New Year paintings suffered a devastating blow in many political movements. Many inheritors were deprived of the right to paint, and the ancient plates were also destroyed. In the past 20 years, although the preparation and production of New Year pictures have been restored, the market has begun to shrink. As a result, some inheritors sold their plates and destroyed their pens and no longer engaged in New Year picture production.
