This poem depicts the bamboo shadow swaying, the wind bleak, and the bamboo shadow obliquely reflected on the window screen. The traveling guests sat there worrying endlessly. I fell asleep at night, but when I saw the bamboo shadow, the wind turned into a dream of rivers and lakes, just like flying flowers. Express the poet's lonely and desolate mental journey.
Dihua: a perennial herb, born by the water, with leaves as long as reeds, purple flowers in autumn and stems that can be woven into foil.
Dry sound: the whistling sound of the northwest wind
