寒蝉一片愁
[hán chán yī piàn chóu]
In ancient times in China, cicadas in winter (or literally, cold cicadas) were rarely seen or even non-existent. So, saying 'cold cicada' carries a melancholy, lonely feeling. Thus, the entire username could be perceived as conveying a profound sadness akin to the sound of the last cicada on a chilly day before hibernation.
