Xuan paper

Xuan paper is renowned for being soft and fine-textured, suitable for conveying the artistic expression of both Chinese calligraphy and painting.

[1] By the Song dynasty, the paper producing industries in Huizhou and Chizhou were gradually transferred to Jing County.

Shengxuan (literally "Raw Xuan"), which is not specially processed, excels in its ability to absorb water, causing the ink on it to blur.

Shuxuan (literally "Ripe Xuan"), however, has a sizing based on potassium alum applied to the paper during production, which results in a stiffer texture, a reduced ability to absorb water, and less resistance to shear stress (meaning that it can be torn much more easily).

[2] The majority of ancient Chinese books and paintings by famous painters that survived until today are well preserved on Xuan paper.
