北城柳絮雨似曾相识南城琉璃月不堪回首
[bĕi chéng liŭ xù yŭ sì céng xiāng shī nán chéng liú lí yuè bù kān huí shŏu]
This internet name combines two scenes from different parts of a city. 'Beicheng willow catkins and rain, seem familiar' (North City's willow fluff and rain, feels like deja vu) suggests memories or familiarity evoked by rain in the northern city. 'Nancheng liuli moon, can't bear to look back' (South City's glassware moon, hard to look back) implies past events under the southern city's moon that bring heartache or regret. The overall feeling is bittersweet.
