北城以北温暖如初南城以南半度温良
[bĕi chéng yĭ bĕi wēn nuăn rú chū nán chéng yĭ nán bàn dù wēn liáng]
Translates as 'Beyond the North City, warm like before, below the South City half a degree of gentle warmth'. This conveys an image of contrasts in temperature and mood. It symbolizes the differences but also continuities between north and south, with underlying warmth.
