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. Nanning GRC line 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). GRC line manufactor It can be divided into light relief and high relief according to the depth of stone removal in image modeling. The bas reliefs are single level statues with relatively simple contents; The high relief is a multi-level statue with complicated contents. 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.

From the perspective of development, sculpture can be divided into traditional sculpture and modern sculpture. Traditional sculpture is a visual, tactile and static three-dimensional art form molded with traditional materials; Modern sculpture uses new materials to make anti traditional four-dimensional, five-dimensional, acousto-optic, soft and dynamic sculptures. According to traditional materials, and according to environment and function, it can be divided into urban sculpture, garden sculpture, indoor sculpture, outdoor sculpture, desk sculpture, shelf sculpture, etc. There are many kinds of sculpture materials, such as clay, stone, wood, metal, gypsum, resin, ivory, etc. Then several categories were developed: wood carvings: wood carvings have a long history. Most of the early themes were centered on religion. In addition to religious icons, they were also used for the decoration of altars and religious places. In countries where wood building flourishes, wood carving develops with architecture. Modern wood carvings have quite diversified styles and features, and artists like to use abstract forms to express them. In addition, wood carving is also an important contributor to the invention of printing. Please see woodcut prints for details; Stone carving: The regions where stone carving is developed have a lot to do with where the stones suitable for carving are produced. The regions where stone carving is developed have a long history of stone carving. In the past, stone carvings were often used as decorations of gardens, signs of doorways, or architectural decorations of mausoleums. Because the stone is thick (not easy to be stolen), and the details of carvings are not easy to be damaged by wind and rain, stone carvings are mostly in outdoor environments. The common stone carving material is marble. There are clay sculptures, ice sculptures, sand sculptures, metal sculptures and pottery.

The art of carving various patterns and images on stones, usually also refers to sculpture handicrafts carved from stones. Chinese stone carving can be divided into bluestone carving, marble carving, white marble carving, talc carving, black crystal stone carving, colored stone carving, pebble carving, etc. The bluestone carvings in Hui'an, Fujian, are famous for architectural decoration and stone lions. The mouth of the stone lion contains stone beads that roll freely, and is famous in Southeast Asia. The marble carving in Yunnan is made from the marble of Diancang Mountain. Its patterns are like colored mountains and rivers, or dangerous peaks and valleys, or waterfalls follow the clouds. The inlaid furniture is unique. White marble carvings in Quyang, Hebei, Fangshan, Beijing and other places were mainly used for palace architectural decoration in the Ming and Qing dynasties, such as Huabiao, stone lions, railings, etc; Modern times are used for decoration of public and memorial buildings, such as the Great Hall of the People, the Monument to the People's Heroes, Chairman Mao's Memorial Hall, etc. Talc carvings in Haicheng, Liaoning Province and Laizhou, Shandong Province use small and cute animals as traditional varieties. The carvings of black crystal stone in Dongkou, Hunan and Lichuan, Hubei are dark and bright. Caishi carving is mainly produced in Qingtian, Zhejiang, Shoushan, Fuzhou and Liuyang, Hunan. Pebble carvings are mainly produced in Lanzhou, Shenyang and other places. Stone carving techniques include intaglio (contour carving), shadow carving, relief, round carving (complete three-dimensional carving without any background), and openwork (also known as openwork). Shadow carving is a unique technique of Fujian Hui'an bluestone carving. It uses steel drills of different sizes to chisel on the bluestone, and uses the size, depth and density of the drill points to express the images of landscapes, birds, animals, people, flowers, etc.

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.
