Modern exhibitions still reproduce ancient poetry and prose or ancient calligraphy, painting and poetry. Different from the early exhibitions, the articles copied now are very long, with no five-character quatrains or seven-character quatrains. In particular, I saw four screens and three eight-foot-high screens, which were full of little people. The calligraphy in the exhibition is like this. Basically, formal beauty is the mainstay, while content is secondary. There are many words in this book.
