In any case, the traditional art of painting and calligraphy mounting (in the picture, it should be machine mounting) is large and small (the sky refers to the size of silk material used for mounting above the work, and the ground refers to the size of silk material used for mounting below the work). The picture in the picture is just the opposite. I don't know whether it is the personal mounting style of the mounter or other reasons, but the meaning of the painting is the same.
