‘斜阳’ literally means ‘slanting sun’ — combining 斜 (xié), meaning ‘oblique’ or ‘slanted’, and 阳 (yáng), meaning ‘sun’ or ‘sunlight’. It evokes the warm, low-hanging light of late afternoon just before sunset, often carrying poetic, nostalgic, or melancholic connotations. Unlike the neutral term 日落 (rìluò, ‘sunset’), 斜阳 emphasizes the visual quality of the light — its angle, softness, and golden hue — and appears frequently in classical poetry, modern literature, and descriptive writing.

This word is rarely used in casual speech or weather reports; instead, it belongs to literary and artistic registers. It often appears in phrases like 斜阳西下 (the slanting sun descends westward) or paired with imagery of solitude, aging, or quiet beauty — for example, an old man sitting alone under the 斜阳, or birds flying across a sky painted by 斜阳. Its emotional resonance makes it a staple in lyrical descriptions of time’s passage and natural transitions.
