The document contrasts Chinese and European art forms through two stories. In one Chinese story, an emperor sees a cave in a wall painting that the painter enters, disappearing along with the painting. In European art, a blacksmith impresses a painter by adding a realistic fly to his work. These stories show that Chinese art aims to transport the viewer's imagination rather than depict reality, while European art seeks to perfectly reproduce a scene through the artist's eyes. The concept of Chinese "shanshui" landscape painting is also explained as representing the Daoist balance of yin and yang energies.
