Does the crease of calligraphy and painting affect the later hand?

It depends on what kind of painting your calligraphy and painting is. Chinese painting has little to do with calligraphy. When mounting, creases will be completely eliminated, as long as your painting is not broken. . If your painting is not framed, take it. If it has been mounted, it can be mounted again, that is, the two layers of paper are separated and supported again. Therefore, as long as the painting has not been mounted, or has been mounted, but it is mounted normally, don't worry, it can be completely restored after mounting.
