The surface of Xuan paper is smooth, the surface texture is not very strong, and there are few impurities, so it is suitable for writing in regular script, cursive script and other fonts. Rough surface, also known as rough surface, can clearly see clear lines and is not suitable for cursive writing.
The respective advantages of different aspects
As far as calligraphy is concerned, Xuan paper has a smooth surface and no obvious lines, which is suitable for fast pen-carrying. For example, cursive script is suitable for smooth surface, not for rough surface. Writing on the glossy surface is usually faster, and most people will practice with the glossy surface of Xuan paper to improve their writing speed. Of course, you should also pay attention to efficiency when you are "fast", because you will have inertia when you run a pen too fast, so it is not suitable for beginners who have not developed good writing habits.
The rough surface of rice paper has obvious lines, so the friction is large. When the brush strokes touch the paper, you can feel the strength of using the pen, which is easier to master. Because there is some resistance when writing, you can also learn to use the pen to cadence and master the structural characteristics of various fonts. The rough surface is especially suitable for running script writing, because there is resistance, so when writing, you will naturally increase your pen strength and make the pop-up nib tight, not as empty as on the smooth surface.
