Most of the jades mentioned in daily life refer to nephrite, and there are many kinds of nephrite products. Generally, they refer to white sheepskin jade, white jade, topaz, purple jade, black jade, jasper, sapphire, ruby and northeast Xiuyu produced in Xinjiang. In the jade carving, the white jade with sheepskin is fine in texture and strong in luster, as white as sheepskin, which can be called "the king of nephrite" and "the crown of white jade". In addition, Nanyang jade, Lantian jade, Hotan jade, agate, crystal, coral, turquoise, lapis lazuli, etc., all belong to the category of nephrite. Later, due to the opening of the Silk Road, the jade produced in Hotan, Xinjiang, was unanimously recognized and began to play a leading role in the processing of royal, official and folk jade. Nephrite gradually evolved into a synonym for hotan jade.

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.
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. 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). 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.
1. Traditional green sculpture shaping: directly pruning the plants with garden art. There are simple geometric shaping (such as sphere, cube, pyramid, cylinder), complex geometric shaping (layered shaping, spiral shaping, etc.), animal shaping and various peculiar shaping (automobile shaping, aircraft shaping, abstract and free shaping, etc.). Common plants include pine and cypress, privet, boxwood, national locust, elm, etc. 2. Grafting: taking a certain plant as the rootstock, grafting plants with different impressions on it, and then making artistic processing of its shapes, such as polychrome chrysanthemum bonsai, polychrome rose bonsai, polychrome peach, polychrome plum, polychrome crabapple, etc. Such as cliff chrysanthemum, tower chrysanthemum, animal shaped chrysanthemum, etc. 2.1 Single plant green sculpture refers to the sculpture formed entirely by one plant or one plant with multiple colors or by grafting multi-color plants. The sculpture has a long viewing period and simple operation. For example, tree sculptures can be kept for a long time only by special pruning, without considering flower changing and water spraying, and the maintenance management is simple. 2.2 Double plant green sculpture refers to the sculpture shaped by two different kinds of plants. The sculpture has a long viewing period and a strong three-dimensional sense, and usually uses the complementary and mutually reinforcing advantages of two plants for modeling. Such as evergreen and deciduous plants, broad-leaved and coniferous plants, lianas and herbs, as well as different colors, species, branches and leaves, such as leaf color, flowers and fruits, branches and stems. 2.3 Mixed plant green sculpture refers to sculpture with three or more kinds of plants. The sculpture has a short viewing period and complicated operation, but it is highly ornamental and lifelike. The common ones are large three-dimensional sculptures, some animal shaped sculptures elaborately composed of flowers, leaves and fruits of different plants according to design requirements, such as peacock, red crowned crane, panda, etc; Or symbolic sculptures with certain cultural connotation and city image, such as idiom allusion sculptures (learning to walk in Handan, dancing at the smell of chickens), Olympic seal, football World Cup, etc.
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.
