紫海棠沉睡暖冬天向日葵开过旧夏天
[zĭ hăi táng chén shuì nuăn dōng tiān xiàng rì kuí kāi guò jiù xià tiān]
It's a metaphor that combines imagery of purple begonia asleep in a warm winter and sunflowers blooming in an old-fashioned summer, suggesting a poetic longing for warmth and vibrant life across contrasting seasons.
