Shallow relief has a low rise, a large compression of shape, a strong sense of plane, and is closer to the form of painting to a greater extent. It does not rely mainly on physical space to create space effects, but uses more painting techniques or perspective, illusion and other processing methods to create more abstract compression space, which is conducive to strengthening the dependency of relief suitable for the carrier. The ancient Assyrians of Mesopotamia were probably the artists who were best at performing art by this means. In a series of "Assyrian Hunting Pictures", they used the technique of bas relief very well to express the lively artistic image with a sense of rhythm and rhythm, and to show the inner feelings of the characters and animals with complex dynamics. The selection of the compression degree of relief space usually takes into account the function, theme, environmental location, light and other factors of the performance object, of which the environment and light factors play a decisive role. Excellent sculptors can always handle these relationships well, so that the works can achieve good visual effects.

Artificial landscape rockery is a kind of mountain built with soil, stone and other materials for the purpose of landscaping in gardens. The rockery has various landscaping functions, such as forming the main landscape or terrain skeleton of the garden, dividing and organizing the garden space, arranging the courtyard, revetment, slope protection, retaining soil, and setting natural flower beds.

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.
