青衫旧巷
[qīng shān jiù xiàng]
'Qingshan Jiu Xiang' suggests a scene where someone is wearing blue clothes, wandering down an old alley, evoking a nostalgic feeling. Qingshan here usually describes the robe of ancient scholars, which can mean a yearning for or remembrance of past times, a sense of loneliness and melancholy in modern days.
