Literature Reference: 青青河畔草，郁郁园中柳。盈盈楼上女，皎皎当窗牖。娥娥红粉妆，纤纤出素手。昔为倡家女，今为荡子妇。荡子行不归，空床难独守。—— 《古诗十九首·青青河畔草》 Green grass by the riverbank, lush willows in the garden. A graceful lady upstairs, radiant by the window. Delicate makeup, slender hands. Once a courtesan, now a wanderer's wife. The wanderer is gone, and the empty bed is hard to keep.
