Write strokes with raw or cooked rice paper.

Xuan paper is divided into raw Xuan, cooked Xuan and semi-cooked Xuan. Among them, cooking refers to smearing with glue and alum during processing. With alum, the ink will remain on the paper, unlike Shengxuan, which absorbs water and is hydrophilic. The function of glue is to fix alum on rice paper. Because of alum, paper is harder than paper and its water absorption capacity is weak, so the ink color will not spread. Therefore, it is suitable for writing small letters, official scripts and regular scripts. However, if the cursive script needs ink painting effect, it can be half-cooked. People who practice Chinese characters for a long time have mastered ink control and can also use semi-mature propaganda.
