Calligraphy paper: Generally, it can be divided into Xuan paper, tassel paper and Yuan book paper. Xuan paper can be roughly divided into raw Xuan, cooked Xuan and semi-cooked Xuan. Personally, I think it's better to practice regular script. It's better to use cooked rice paper in lower case, semi-cooked rice paper in middle case, and write big characters such as list books and couplets with students' announcements.
Usually practice at home. The author mainly uses textured paper, and it is easier to use manual raw edges, while the machine-made raw edges are thinner and the textured surface is good.
I wish you get out of your confusion as soon as possible!
