守一座空城空一池烟雨梦一场倾城倾半世浮华
[shŏu yī zuò kōng chéng kōng yī chí yān yŭ mèng yī chăng qīng chéng qīng bàn shì fú huá]
It loosely means “Stay in an empty city alone with the rain-covered dream. Experience once a life-changingly magnificent splendor.” The overall feeling is very melancholic, possibly hinting at loneliness, past glory and loss.
