南城旧梦北国忆昔
[nán chéng jiù mèng bĕi guó yì xī]
Translated as 'Old Dreams of the Southern City and Memories of the Northern Country,' this phrase evokes themes of nostalgia and distant, unattainable pasts. It contrasts the bustling city life in the south with serene rural settings in the north, emphasizing a connection between two disparate places.
