顾北清歌寒
[gù bĕi qīng gē hán]
'Gu Bei Qing Ge Han' seems more like an evocative, mood-oriented internet nickname rather than straightforward denotations of terms. It suggests a person with melancholy or solitude in their hearts still chooses to embrace life in a clean, transparent way. Literally speaking, Gu means 'look after'; Bei, a direction; 'Qingge' clear singing; Han 'cold', together painting a picturesque scenery of someone sings clearly in northern chill.
