"The glow of sunset still fills the sky" comes from a poem by Liu Yuxi, meaning the evening scene of sunset is equally magnificent

"The glow of sunset still fills the sky" comes from "Reply to Letian's Poem on Aging" by the Tang dynasty poet Liu Yuxi. The full line reads, "Do not say the sun is late setting behind the mulberry and elm trees; its glow of sunset still fills the sky." Literally, it means do not say the sun has already set between the mulberry and elm trees, for the sunset glow it casts can still light up the entire sky. This line of poetry was later widely quoted to describe how a person in old age can still shine and accomplish things.

In terms of imagery, this line breaks away from the literary convention of lamenting one's twilight years, painting the setting sun and sunset glow as expansive and powerful. Writing about the setting sun as well, Li Shangyin focused on sighing over how swiftly time passes, with a tone leaning toward melancholy, whereas the sunset glow in Liu Yuxi's writing is spirited and open-minded. This positive attitude toward life is precisely why it has been passed down through the ages.

In gardening life, this line is also often used by flower growers to describe the scene of flowers blooming in abundance. For example, the tiny, delicate flowers of baby's breath densely cover the branches, and at peak bloom, seen from a distance, they look like a spread of colorful sunset clouds. Planted on a balcony or in a courtyard, they easily create an atmosphere of radiance filling the view, and many flower enthusiasts also borrow this line to name their potted plant photos and flower border vignettes.

In application, "the glow of sunset still fills the sky" commonly appears in calligraphy works, birthday congratulatory inscriptions and occasions honoring the elderly, and also often appears in articles describing evening scenes or seas of flowers. Those who love growing flowers can draw on this imagery, choosing varieties with abundant blooms and long peak flowering periods to arrange at home, so that flowers may bloom across the sky through all four seasons.
