The art of mounting ancient paintings and calligraphy has a long history, from silk paintings and silk books in the Warring States Period to large silk scrolls in the Western Han Dynasty, it has a history of more than 2,000 years. According to Zhang Yanyuan's "Records of Famous Paintings of All Dynasties", mounting technology has existed since before the Jin Dynasty, which is the earliest existing historical record of mounting. From the Tang Dynasty to the Song Dynasty, mounting technology entered its heyday. After the Ming and Qing Dynasties, due to the differences in the style, quality, and process operation of calligraphy and painting mounting in different regions, mounting has strong regional aesthetic characteristics, and each has its own strengths. The art of mounting is generally divided into four major schools: Su, Shanghai, Yang, and Beijing. The characteristics of Su mounting are that the mounting pieces are flat and soft, the color matching is simple and elegant, the mounting is cut and pasted, and the restoration is done in a proper way. It has the reputation of "the best Wu mounting, and no other place can match it". "Beijing mounting" was formed under the direct influence of Su mounting. Due to the influence of the court, its mounting pieces are characterized by gorgeous colors, giving people a sense of nobility and magnificence. The Yangzhou mounting style appeared later than the Su style. Its characteristics are good at imitating antiques and repairing old paintings. No matter how old or broken the old paintings are, once they are mounted, they can achieve a seamless state. The Shanghai mounting and restoration style is between the Su and Yang styles. It absorbs the advantages of the two schools and develops them, thus forming its own characteristics and is known as a rising star in history. Painting and calligraphy mounting is a decorative art and the basis for painting and calligraphy restoration. To complete the mounting of a painting and calligraphy work, it is necessary to go through more than a dozen processes such as support, piercing, inlaying, back support, calendering, pole mounting, and stripping. The restoration of ancient paintings and calligraphy is a very complex and difficult process. First of all, according to the different works to be restored, there are basic processes such as: mildew removal-lead return-washing-unmounting-digging-full color-joining pen-filling powder. The mounting of ancient paintings and calligraphy is a unique art extended from painting and calligraphy. It is a traditional pure handmade artistic creation activity that combines knowledge of history, literature, calligraphy, painting, color, physics and chemistry. It is of great significance to the preservation and promotion of traditional Chinese painting and calligraphy.
