北城以北荒芜之地南城以南孤城之梦
[bĕi chéng yĭ bĕi huāng wú zhī dì nán chéng yĭ nán gū chéng zhī mèng]
This could mean 'Wasteland north of North City, Dreaming lonely city south of South City'. Imaginative, abstract, possibly reflecting the author’s contemplations between desolation and aspirations in different parts of their life journey or dreams.
