Known as a "blank scroll", it means that the white paper has been mounted, written on the paper, and directly hung or given away. Blank scrolls are very convenient and cheaper than framed works. But you should also pay attention to writing blank scrolls, because once you make a mistake or write badly, the whole scroll will be useless. It can be said that using blank scrolls has advantages and disadvantages, but be careful, the advantages still outweigh the disadvantages.
