长街长灯火阑珊短巷短良人未归
[zhăng jiē zhăng dēng huŏ lán shān duăn xiàng duăn liáng rén wèi guī]
'Long street with long lights and short alley without return of the beloved' indicates melancholy over someone who hasn't returned yet. There's also an allusion to classical poetic imagery, conveying loneliness and anticipation in a romantic context.
