北城以北天未晴南城以南雪未凉
[bĕi chéng yĭ bĕi tiān wèi qíng nán chéng yĭ nán xuĕ wèi liáng]
Roughly translating to 'North of the North City the sky remains overcast while south of South City snow stays unfallen/warm.' This is poetic expression likely referencing melancholic mood, unchanging conditions, or geographical/personal contrasts using weather imagery.
