1. Carve paper-cuts; ? It is usually a monochrome paper-cut work cut and carved from red paper, black paper or other materials. The characteristic of orthographic paper-cutting is to keep the outline of the manuscript and cut off the blank parts outside the outline. Every thread of it is interrelated, which affects the whole body. ? 2. Incision paper cutting? ; The characteristics of negative paper-cutting are just the opposite of positive paper-cutting, that is, the outline of the manuscript is cut off and the parts outside the outline are retained. ? Therefore, the characteristic of gravure paper-cutting is that its lines are not necessarily interrelated, but the whole work is massive. ? 3. combination of yin and yang? ; The combination of yin and yang is based on the needs of the relationship between reality and reality in the painting, and the method of cross-carving of yin and yang can make the picture more abundant and clear. ? 4. Silhouette? ; It expresses the image through the outer contour of the object, so it pays the most attention to the beauty and shape of the outer contour. Mr. Xu Beihong, a famous painter and art educator in China, once said that silhouette shows "an advanced plastic mind" in the form of "paper-cutting". The popular "silhouette painting" in Britain is to cut out the shadows of objects with black paper to form a picture with black shadows. This silhouette painting later developed into a film form. The silhouette of the former GDR, The Mountain God and the Thresher, is one of them. In fact, China's early shadow play and paper-cutting art also learn from each other and influence each other. Therefore, as an art form, it is unique. ? Color paper-cutting? 5. Color paper-cutting? ; Color-matching paper-cutting is a widely used expression in paper-cutting art, which is generally all kinds of colored paper needed for collage of finished positive engraving. The main materials commonly used are thick paper, or some advanced materials such as satin and flannel. And the color should be darker, so that it can be set up easily. A kind of "copper lining" in Foshan, Guangdong Province is that the main manuscript is carved with gold paper, and each part is lined with red, lake blue, grass green and medium yellow, which looks magnificent. ? 6. Little paper-cutting? ; Dotted paper-cutting is also called dyeing. The finished product cut and carved with raw rice paper is decorated with various colors with a brush. If several layers are to be lit together, a little wine should be added to the color pigment to facilitate color penetration. When coloring, pay attention to one color and then paint another color to avoid color confusion. However, in order to achieve the percolation ratio effect of two colors, it is not necessary to wait for one color to dry before painting another color. Usually, another color is painted when the first color is half dry to achieve percolation effect. Dotted paper-cutting usually adopts intaglio method, which is convenient for large-scale dyeing. Dot-colored paper-cut has a strong color and a strong local flavor, and it is most famous for its dyed paper-cut in Yuxian County, Hebei Province, China. On the basis of inheriting the traditional stippling in Yuxian, China Pingyang dyed paper-cut in Zhejiang absorbed the application methods of light and color in western watercolor painting, and explored a new way for the innovation of stippling paper-cut. ?
