Shengxuan is a kind of ordinary rice paper, which has no other treatment. There are many "wrinkles" on it, which helps to absorb ink and make the ink more obvious. It is suitable for freehand brushwork and line painting.
Cooked rice paper is treated by brushing a layer of alum on raw rice paper, which loses its curing and water absorption performance, so cooked rice paper is suitable for meticulous painting, letter opening, official seal and so on.
