Can the subsidy for digging holes in wrong calligraphy on rice paper be mounted?

it can be mounted, but if you are not a professional mounting artist, don't do it yourself. Send your work to a professional mounting shop for mounting. Known as "digging and mounting" in this industry, it must be mounted by hand, not by machine, and it needs to be operated by experienced professionals. If you meet a skilled mounter, you won't see it if you don't look carefully after mounting it.
