北城寒笙南街离梦
[bĕi chéng hán shēng nán jiē lí mèng]
Translating to 'Chilly Flute of North City, Parting Dream of South Street', this nickname reflects contrasts in direction (North and South), emotion (chill, parting) and atmosphere (flute - melancholic, street). It gives a very poetic, dreamlike quality which seems like it would belong to someone who appreciates romantic literature or poetry, possibly someone with nostalgic feelings, longing for past memories or love.
