China's traditional copying and sketching.

This work is a classic of Song people's sketches and is called "Butterfly of Begonia" by anonymous authors. I don't know the original volume of this picture, and there is no author's surname. Investigating his painting of begonia leaves and butterflies should be regarded as the work of people in the Painting Academy at the end of the Northern Song Dynasty. Butterflies are lively and interesting. Although it is an institutional painting, it is not vulgar. ? The picture shows Haitang in March, and butterflies are dancing among the flowers. When copying, we should pay attention to the characteristics of this kind of trace, especially the change of brush stroke thickness. The wires used are basically iron wires. When the leaves are hooked, you can consider using a thick brush such as hanging snow on the green hills to outline them. In color setting, it should be noted that the color setting of butterflies is almost boneless, and the white powder of flower heads should not be too thick. We can use the method of pulling the flower heads apart and painting the background color several times. Otherwise, if the white powder of the flower head is too thick, the later color matching will be more troublesome. . . . .
