Sculpture refers to ornamental objects and monuments which are used to beautify the city or to commemorate the significance, with a certain meaning or symbol. Sculpture is a kind of plastic arts.

Sculpture is the branch of the visual arts that are made of a variety of plastic materials. It operates in three dimensions. The process of creating a sculptural work involves two major categories: carving and modeling. So, the sculpture is also known as engraving. When making sculptures, it embraces varied methods and techniques, such as cutting, carving, modeling, chiseling, shaping and casting. According to the content and functions, sculpture can be roughly divided into monumental sculpture, urban sculpture, garden sculpture, religious sculpture, artistic sculpture and so on. And according to the types, it can be categorized into avatars, portrait busts, half-length, full-length, and sculptural group.

According to basic traditional forms of sculpture, it exists in 3 dimensions: round, relief and openwork sculpture. Round sculpture, also called "free-standing", is the three-dimensional art that are not attached to any surface and can be looked at from every angle. The sculpture in the round is a purely solid image, standing freely in the space. So, during the creation, the sculptor must consider the aspects of volume and weight, as well as the different angles so that viewers can see the artwork from all sides. Relief sculpture, also known as "convex carving", is a projection artistic image arranged on a flat surface. It is often distinguished according to how high the figures project from the surface, encompassing high relief and bas-relief. High relief, remains to the background with high projection, while low or bas-relief, projects slightly from the background. Openwork sculpture, it is defined between round and relief. It is made on the basis of relief sculpture, with background carved away, but it is still attached to the surface, which looks like a round sculpture carved on a flat surface.
