落幕街灯终究天黑
[luò mù jiē dēng zhōng jiū tiān hēi]
In literal terms, this phrase means 'Streetlights at sunset ultimately fade into night.' Metaphorically, it conveys feelings of loneliness and inevitability; no matter how much one lingers in twilight (often representing better moments or times), darkness will always come eventually. The tone can be melancholy or pessimistic.
