What paper is used for Liu Zhong's messenger post and four poems? Why blue?

Liu Zhong's messenger posts and four ancient poems are all made of porcelain green paper. This paper is blue because it is made by a series of dyeing processes. In Ming Dynasty and Song Dynasty, it was a gorgeous paper, which was difficult for ordinary people to buy and expensive. Moreover, the extraction of pigment was not developed at that time, so it took a lot of time and more processing procedures to make paper.

Compared with other lightweight papers, this kind of dyed paper can be said to be very heavy, so it is often used to copy some literary works. Even if there is more ink, it's hard to do it? Come back through the paper . Of course, some rich writers also chose to create their own works at that time. Writing their own words on such paper is actually a pleasure, and such thick paper can also facilitate the circulation and preservation of their works in the future.

Moreover, this kind of paper can not only copy such words or create works, but also be used for painting. Many people who like to paint Buddha statues will choose this kind of paper to paint. When they paint, they don't just use black ink. Instead, I chose to find some gold powder to paint. Gold powder ink and such indigo paper can be said to provide some color and charm for his works.

In some ancient tombs, we also saw the appearance of such works, such as Liu Zhongshi and Four Poems. These two works are obviously created with this blue paper, which seems to make people feel that the works are relatively complete, and when people appreciate such works, they can also feel the wisdom of the ancients in creating this paper. Of course, there are many works created with this kind of paper, which show the cultural level and literary accomplishment of the literati and are a relatively complete presentation of the works.
