"The flying flowers at home are as light as a dream, and the endless rain is as fine as sorrow" comes from "Huanxisha" written by Qin Guan, a poet in the Song Dynasty.
Huanxisha
[Song] Qin Guan
The desert is light and cold, with small buildings. Silver hooligans are like poor autumn. Looking back at the screen, the light smoke, the flowing water, the mood is faint. ?
Outside the window, the flowers are dancing freely, just like in a dream, the rain is falling and drifting aimlessly, like melancholy. Look again, the curtain of jewelry hangs on the silver hook at will.
Translation:
In the chilly weather in spring, I boarded the small building alone, and the morning sky seemed like a cloud in late autumn. The light smoke on the indoor painting screen is faint, and the water is gurgling.
The petals flying freely in the sky are as light as a dream at night, and the rain in the sky is as thin as the sorrow in my heart. Go back indoors and hang the curtains with small silver hooks at will.
