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 finds 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.

Circular sculpture, also known as three-dimensional sculpture, refers to non compressed three-dimensional sculpture that can be viewed from multiple directions and angles. Sculpture is the overall expression of art on the sculpture. The viewer can see all sides of the object from different angles. It requires the sculptor to carve from the front, back, left, right, top, middle and bottom. The techniques and forms of round sculpture are also varied, including realistic and decorative, concrete and abstract, indoor and outdoor, shelf and large city sculpture, colored and non colored, etc; The contents and themes of the sculptures are also rich and colorful, which can be characters, animals or even still life; The materials are more colorful, including stone, wood, metal, clay, gypsum, textiles, paper, plants, rubber, etc. It is mostly used in fountains, gardens and indoors. Because the round sculpture works are very three-dimensional, vivid, lifelike and vivid, the selection of stone materials is strict. First of all, we should design the shape of the sculpture, and pay special attention to the fact that the sculpture must have a proper proportion with the real object from length to width to thickness.

Auxiliary tools for wood carving: mainly hammer, wood file, axe and saw. The purpose of the axe is to cut a large amount of wood with the help of paring. Pay attention not to use too much force when cutting. Do not cut straight up and down. The edge of the axe should be kept at about 45 degrees with the vertical wood grain, otherwise the wood will crack. Hainan GRC component wood file is mainly used in the fine blank stage of round carving, which can replace the flat knife to smooth the chisel marks for polishing; It can also take the place of round knife or oblique knife for hollowing. The function of the wood file is also that it can quickly adjust the modeling structure in a large area, and can be used in combination with the carving knife to make the turning and turning of the figure's clothing patterns vivid and smooth, with both virtual and real effects. The shape of hammers for wooden sculptures in Hainan is flat, flat, wide and square. The dimension of hammer face can be controlled at about 7 × 5.5 × 2.5 cm. Too narrow or too thick will affect the accuracy of the hammer's landing point and the uniformity of force. There are two kinds of hammers: wooden hammers and iron hammers. The wooden hammers generally use hardwoods with a large proportion of wood, such as mahogany, boxwood, sandalwood, beech and fruit trees. The specifications can be controlled at 27 cm in length, 55 cm in width and 45 cm in thickness; The grip is round and slightly flat, and the size is suitable for holding in the hand.
