1. Representativeness. Collections should first consider those representative works. For example, the author's masterpieces in various periods, influential works in various regions, various styles, genres, artistic events, and various artistic periods. At the same time, it is also important for artists to have outstanding personal styles. In addition, certain factors such as the creativity, popularity, and status of the sculptor should be considered. These factors are directly related to the value of the sculpture and the potential for future appreciation.
2. Aestheticism and innovation. Many sculpture collectors are still immature. Most of them are buying on the basis of their own interest and intuitive judgment. They equate the aesthetic standards in life with the aesthetic standards of art appreciation. Realism masters such as Rodin, Mayor, and Burdel, their works are not only realism and aesthetics, but also pay attention to the shape and space processing, emphasizing the sense of volume and space, as well as the expression of the personality and inner world of the characters, while emphasizing innovation. Reflect a strong personal style. In the period of classicism, the language of sculpture was the language of the human body. The human body has always been the only important proposition of sculpture. However, Rodin shifted his attention from the vivid changes in human skeletal muscles and the conflicts of the characters' emotions to the clumps and sense of form formed in the natural movement of the human body, forming his own unique style of human sculpture.

3. Decorative. The decoration of ancient Chinese sculpture is quite prominent, because its decoration reflects its aesthetics and artistry. Whether it is a figure or an animal, whether it is Ming ware art, religious statues or architectural decorative carvings, they generally reflect the long tradition of decorative interest. The most notable examples are the sitting Buddha in the open air in Yungang, Northern Wei Dynasty, the evil spirits of the Southern Dynasty and the stone lion of the Tang Dynasty in the appreciation textbook. The symmetrical sitting posture of the Buddha statues and the patterned cassock pattern processing make them show a strong decorativeness and better play their functions as architectural decorations.

4. Painterly. Sculpture and painting are a pair of brothers, both conceived in primitive arts and crafts. Since the age of painted pottery, plastic paintings have complemented and closely integrated each other. After the two are mature, they still "shape the quality" and add color to the sculpture (called "Zhuangluan" in technical terms) to improve the performance of the sculpture. Many of the existing sculptures of the past dynasties are clay sculptures, stone carvings and wood carvings. Today's sculpture art is completely Westernized, and no more color is added, but folk sculptures still maintain the tradition of makeup.
