Liquidambar printing and dyeing is simple and exquisite, and is known as "Bouyei cultural relics that do not need to be unearthed". As one of the oldest folk printing and dyeing techniques, the liquidambar printing and dyeing technique has a unique atmosphere and pattern, embodying the labor wisdom of the Bouyei people. In 2008, it was selected into the second batch of national intangible cultural heritage protection list in my country. Liquidambar printing and dyeing techniques are cumbersome and are pure manual craftsmanship. There are processes such as selecting materials, making liquidambar oil, mixing dyes, drawing patterns and dyeing. The production of a liquidambar dyeing work requires at least nearly ten days of effort. Selecting fabrics. Traditional liquidambar printing and dyeing works mostly use self-woven homespun cloth, and then select and cut the size of the fabric according to the purpose. Making liquidambar oil. Liquidambar oil is mainly composed of liquidambar resin and butter, among which liquidambar resin is secreted by local liquidambar trees. The best time to collect liquidambar resin is the rainy season every year, when the liquidambar trees grow luxuriantly and the resin secretion is the most prosperous time of the year. To make maple oil, put maple resin into a hot iron pot, wait for the maple resin to completely dissolve, add an equal amount of butter, and then stir in the pot with a small wooden stick to make the two fully dissolved and interpenetrate each other. The addition of butter increases the toughness of the maple resin, and at this time the maple resin completes a gorgeous transformation, which makes it easier to degrease the fabric after dyeing. Prepare dyes. The maple printing and dyeing uses plant dyes such as indigo, which is also called indigo. It is a plant dye made by extracting pigments from the leaves of the plant indigo. The key to the production of indigo is the proportion of lime. The control of the proportion is very important. It should not be too much or too little. This control experience directly affects the quality of the final indigo coloring. Draw patterns. When drawing patterns in maple printing and dyeing, there is no reference to any patterns or textures. Whether it is curved or straight, thick or thin, the beautiful food printing and dyeing patterns all depend on a pair of hands and experience. Dyeing. Put the painted works into the dye vat with the dye prepared in advance for dyeing. When the works are completely soaked and sunk into the vat, pick up the works and hang them to dry after two or three hours, so that the dye on the fabric is fully exposed to the air and oxidized. Repeat the soaking three times. With each deepening of the immersion, the works have an elegant and thick color. The dyed works are finally degreased and dried in boiling water, and a delicate and beautiful maple printing and dyeing work is presented before the eyes. Typical patterns on traditional maple printing and dyeing works include "Double Phoenix Facing the Sun", "Carp Beads", "Big Bottle Flowers", "Longevity Peach Flowers", "Pomegranate Flowers", "Reverse Winged Butterflies", etc. The simple and elegant patterns incorporate the simple and innocent feelings of the Buyi people and their infinite yearning for a better life. The materials used in the maple printing and dyeing process are all natural, and the main materials are extracted from the maple tree, hence the name. This unique handicraft with a history of more than 120 years has a long history and is still popular in Huishui, Majiang and other areas of Guizhou Province. The Buyi people living here flexibly apply the maple printing and dyeing technology to their daily lives. Whether it is dresses, hanging ornaments, or daily sheets and quilts, they all display the exquisite maple printing and dyeing technology. When a local girl gets married, the number of maple-dyed quilt covers is used to express the degree of love for the daughter. Currently, there are only 12 elderly people who know the maple dyeing technique. The youngest of them is over 50 years old, and the oldest is nearly 80. Among the 12 maple dyeing artists, only the brothers Yang Guanghan and Yang Guangcheng have mastered the most core technology.
