Is calligraphy and painting mounted or mounted?

The advantage of installing the shaft is that you can take it out if you want to hang it, and roll it up if you don't want to hang it, which does not take up space. The disadvantage is that it is easy to get dirty, concave and bulging. The mounting frame is bonded to four sides, but not all sides. When you want to remove it, use a knife to cut a small mouth along the edge of Zi Ling, which won't hurt the painting heart. It can be removed like paper cutting. Mounting frame takes up too much space, but because there is a film or glass outside the frame, calligraphy and painting can be as good as new for a long time. In short, if there is room to hang, it is better to make a frame, which is more expensive, with four feet 150. In addition: never machine-installed, machine-installed is a disposable chemical glue. A good painting machine is mounted, and the painting is white and blind.
