What's the difference between living and writing calligraphy?

Raw rice paper can produce curing effect. Cooked rice paper coated with alum and bone glue is mainly used for meticulous painting. Paper needs to be preserved for a period of time, especially the real rice paper. The longer the better, but it must be preserved. Don't be exposed to the sun for a long time. When the paper is not used, it should be wrapped in three layers of newspaper. Otherwise, rice paper will become stiff and not cure well.
