守一座城等一个旧人
[shŏu yī zuò chéng dĕng yī gè jiù rén]
'Guarding a City Waiting for an Old Person/A Former Loved One': It reflects dedication and loyalty towards the past. The person might be stubbornly keeping promises or maintaining memories associated with a loved one they are waiting for. A profound sense of nostalgia mixed with unwavering loyalty can be read from it.
