Feather: Feather.
Rush: twice, twice.
Wet phase is heavy: wet twice (rain is wet, water on the soil is wet. )
The feathers dropped by swallows skimming the water surface floated on the water surface alone, and the flowers that fell after being wet by rain fell on the wet soil and were wet twice.
This poem is antithetical, clear and desolate, and graceful in style. At the same time, it also shows Song Huizong's loneliness (cold rotation) and helplessness (wet weight) at that time.
If we can find out the creation date of this cursive fan, we can better analyze Song Huizong's mood according to his situation at that time.
