天还蓝风还暖少女我还在旧街冷巷死胡同少年可在
[tiān hái lán fēng hái nuăn shăo nǚ wŏ hái zài jiù jiē lĕng xiàng sĭ hú tóng shăo nián kĕ zài]
The poetic phrase 'the sky is still blue, the wind is still warm, I'm still that girl from the old street, narrow lanes, and cul-de-sacs but where can the boy be found?' implies longing for things/persons from the past in a context that evokes strong nostalgia.
