Root carving is to create artistic works of characters, animals, utensils and other artistic images through conception, artistic processing and process, taking the autogenetic form and distorted form of tree roots (including tree bodies, nodules, bamboo roots, etc.) as the object of artistic creation. Root carving art is a kind of plastic art that discovers natural beauty and shows creative processing. The so-called "three parts of labor, seven parts of nature" means that in the creation of root carving, most of the natural forms of root materials should be used to express artistic images, and a few of them should be artificially processed and modified. Therefore, root carving is also called "root art" or "root art". The basic technique of root carving is to use exaggeration, fantasy and abstraction to reflect real life. To be specific, it is to make a comprehensive and careful observation of the selected root material and make a clever idea. By virtue of its shape, texture, knots, concavity and convexity, curvature, holes, and so on, it is a bold idea to combine the virtual with the real. The line seeks the usable value of the material itself with a variety of themes and contents, and is good at finding the extraordinary from the ordinary, and gradually determines the overall image of the creation. It is very important to make clear the creative idea and imagine boldly for the root generation creation.

Relief is a kind of sculpture. The sculptor carves the image he wants to shape on a flat plate, making it separate from the plane of the original material. Relief is the product of the combination of sculpture and painting. It deals with objects in a compressed way, and displays three-dimensional space by perspective and other factors. It is only for one side or two sides to see. The reliefs are usually attached to another plane, so they are used more in architecture and can be seen on utensils and implements. Due to its compression characteristics, it occupies less space, so it is suitable for decoration in a variety of environments. In recent years, it has played an increasingly important role in urban beautification. Nanjing Abstract sculpture The relief is as rich and colorful as the round sculpture in content, form and material. The materials of relief include stone, wood, ivory and metal. The relief is a semi vertical sculpture whose image shape protrudes from the stone surface (as opposed to the relief). According to the different depth of stone removal in image modeling, it can be divided into low relief and high relief. The bas reliefs are single level statues with relatively simple contents; The high relief is a multi-level statue with complicated contents. recommend Abstract sculpture The carving technique and expression style of relief are basically the same as those of round sculpture. Many ancient and modern large-scale memorial buildings, high-end mansions and private houses are equipped with such decorations. Their main works are wall blocks, flower windows, dragon columns (early) and column bases.

Wood carving is a kind of sculpture, which is often called "folk craft" in our country. Wood carving can be divided into three categories: three-dimensional round carving, root carving and relief carving. Wood carving is a kind of work separated from carpentry, which is classified as "fine carpentry" in our country. Folk art varieties classified by carving materials. Generally, the tree species with fine and tough texture and not easy to deform are selected, such as nanmu, red sandalwood, camphor wood, cypress, ginkgo, agarwood, mahogany, longan, etc. The tree root carving art in natural form is called "tree root carving". Wood carving has round carving, relief carving, engraving or several techniques. Some are also painted to protect wood and beautify it. Generally speaking, tools for wood carving creation, such as saws, wood files, chisels, carving knives, flat shovels, axes, wood drills, wood hammers, planes, etc., can be used for root carving creation. In addition, you also need basic tools such as scissors (scissors for pruning), knives, brushes, sandpaper (cloth), coarse and fine cloth, cotton yarn, rope, etc. During special processing, such as fire roasting, steaming, and insect prevention, some tools are also needed, which can be used in general families instead of other tools.

Marble, granite, Hui'an stone, Qingtian stone, Shoushan stone, Guicui stone and other materials are generally used for stone carving. Granite and marble are suitable for carving large statues; Qingtian stone and Shoushan stone are rich in color, which are more suitable for small stone carvings. There are many ways to make stone carvings. According to the nature of stone materials and the habits of the carvers, stone carvings can be roughly divided into two types: first, traditional methods. Conception, composition, modeling and stone carving are all done by individuals alone. For large-scale carving of lines, the horizontal and vertical lines shall be drawn on the stone, the grid shall be made to take materials, and the simple measurement and positioning method shall be used for carving. The second is to adopt a new process, that is, first make a clay sculpture, turn it into a plaster statue, then take the plaster statue (model) as the basis, rely on the point shaped instrument, and then carve it into a stone statue.
