旧衫故人青衫佳人
[jiù shān gù rén qīng shān jiā rén]
Translated directly as 'old clothes, old friend, blue robe, beautiful person,' this evokes an imagery of reminiscing past times, friends, and experiences (like the old clothing). Also implies nostalgia for better, more romanticized times and people. A user picking such a nickname might enjoy reflecting fondly on the past.
