守一座空城等一个旧人听一曲笙箫舞一支悲凉
[shŏu yī zuò kōng chéng dĕng yī gè jiù rén tīng yī qŭ shēng xiāo wŭ yī zhī bēi liáng]
Means 'guarding an empty city waiting for a former love while listening to a bamboo flute dance to melancholy tunes.' Reflects the longing for past memories, lost love, and lingering emotions tied to people or times that once held significance.
