The picture described in this poem is beautiful, and the scenery itself has a hazy feeling. Plus the image of the person you are looking for can't be captured, which is even more subtle and endless. This hazy beauty in The Book of Songs is similar to China's ink painting. The ink painting "Danqing" uses light ink to smudge on rice paper, creating a dense scene, and the characters are lifelike from a distance; If you look carefully, it's fuzzy.
