Why do people like to use rice paper when writing Chinese calligraphy?

Among many kinds of paper, why is Xuan paper only favored by painters and painters? Because China's paintings and calligraphy pay attention to artistic conception, the paper is not slippery or stagnant. If the paper is too slippery, it will "write like a horse on ice", and even the best horse can't run or jump. If the paper is too sluggish, it just can't flow naturally. However, Xuan paper is neither slippery nor stagnant, and its smoothness is moderate. Paper is "white, delicate, soft, homogeneous and durable" and "can absorb water and ink", which is very suitable for painting and calligraphy. Another major feature of suitable paper for calligraphy and painting is that it can keep the color itself bright and bright, and will not change color or dim, which brings out the best in each other, which best reflects the unique mystery of China's calligraphy and painting.
