Cooked rice paper is brushed with alum water, which absorbs water slowly and is suitable for creating some meticulous paintings.
When choosing paper, the texture is the most important. Poor quality paper is not only easy to damage the pen, but also difficult to keep. Famous papers in ancient and modern times are famous for their quality, such as "Integrity Hall paper is as dense as printing", and the jade board claims to be "flexible and durable". The toughness and compactness of paper are the best, which can be known by visual inspection when choosing.
Paper is not white, because the raw materials are not good, or the water quality is not good. The extremely white jade board is made of ebony, and the bookcase is made of "Huan flower bed water", all of which are examples. If it is dyed, it must be pure white and natural paper. However, the dyed paper is not easy to spread for a long time. If you want the works to be put in the museum in a hundred years, you'd better avoid using them. White is not white, you can understand it with your eyes. I don't need to say more about this.
The surface of paper can be divided into smooth and rough; Smooth and solid pen, but if it is too slippery and light, there is no pen power, while if it is rough, it is easy to get pen power, but if it is too rough, it is difficult to write and damage the pen tip. The so-called "fine but not astringent" is also true. This can be distinguished by vision and touch, so I won't say much.
The paper must be able to feed ink, otherwise the ink floats on the paper, which is easy to fall off and cannot be stored for a long time. Generally speaking, Xuan paper has strong ink absorption, while paper is the opposite. Ink absorption is too strong. If you use the pen slowly, dots and pictures will become ink balls. But if the ink absorption is too weak, the ink is not easy to enter the paper, so it is not suitable. Therefore, when choosing paper, we should consider the style of the book and the speed of personal pen lifting. If only ink could feed paper but not "balls". If the store allows, try it with ink. Just try it and you'll know.
