According to Baidu's Chinese, the poem "Autumn Winds are Cool, Grasses and Trees are Cool, Dew is Frost" comes from "Two Songs of Swallow Songs" by Cao Pi, the emperor of Cao Wei during the Three Kingdoms period. The translation reads: The autumn wind is sluggish, the weather is cool, the grass and trees are blown down by the wind, and the white dew condenses into frost.

Part of the poem "Two Songs of Swallow Songs" (Wei - Cao Pi): The weather is cool in the autumn wind, the grass and trees are shaken by the wind, and the dew turns to frost, and the swallows are leaving their homes and the swans are flying south. I'm sorry to hear that you've been away for a long time, and I'm sorry to hear that you want to go back to your hometown, but I'm not sure why you're staying.
