雨落繁华市雪飘凄凉城
[yŭ luò fán huá shì xuĕ piāo qī liáng chéng]
It can be understood as 'Rain Falling In The Prosperous City While Snow Is Drifting In Desolate Town'. A vivid description using contrasting elements to highlight two distinct atmospheres, which might stand for varied moods or states - possibly happiness vs sadness or prosperity vs adversity.
