Can the paper be folded before calligraphy is mounted, and will there be traces after mounting?

Before calligraphy is mounted, Xuan paper can be folded, and there will be no trace after folding!

This is due to the flexibility of rice paper. If we knead the raw materials into a ball and iron them, we can still restore the original appearance. Therefore, when you create a work in birthday promotion, even if the written work is rubbed at will after the ink is dried, the work still presents a flat visual effect after mounting.
