顾北凉城安以陌望南旧梦以成歌
[gù bĕi liáng chéng ān yĭ mò wàng nán jiù mèng yĭ chéng gē]
The meaning is deep within its context, suggesting a person ('Gu Bei') reminiscing past times in the northern city ('Beiliang'), finding comfort and singing songs of southern memories or past lovers ('An Yi Mo Wangnan jiumeng yichengge'). It tells an evocative narrative filled with nostalgia, reflection on lost loves or dreams, and the passage of time, creating melodies out of such tales.
