Paper with a brush and calligraphy works are generally written on Xuan paper, because Xuan paper can best express the dryness and wetness of ink. However, the raw material of rice paper is Dalbergia bark, and the production process is complicated. The ancients said that "it is not easy to cut paper, but it is seventy-two", so rice paper is expensive. Beginners generally use cheap paper such as meta-book paper and tassel paper. Now the paper industry is very developed, but smooth white paper such as coated paper and road paper is not suitable for practicing calligraphy, because the paper surface is too smooth, and the written paper is easy to float, so it is impossible to practice pen power. Among the machine-made paper, the old newspaper is rough, the ink absorption performance is ok, and the novice can completely recycle it.
