As long as it is kept under normal conditions, it will not be damp. First of all, it will not turn yellow and break like ordinary paper when it is touched for a long time.
Second, the painting and calligraphy mounting process is mature. There is an old saying:? Three-point painting and seven-point mounting. ? The preservation of calligraphy and painting doesn't mean that you can put it there after painting, but you should frame it. The problem of how to mount calligraphy and painting has been puzzling the ancients. They put paintings and calligraphy in different places and tried thousands of times to get this result. And can be repeatedly installed all the time. The reason why some paintings and calligraphy can be preserved until now is related to repeated mounting.
