感谢我不可以拥抱的你背影
[găn xiè wŏ bù kĕ yĭ yōng bào de nĭ bèi yĭng]
Thank you, the back view of you I can never hug - It conveys a bittersweet sentiment towards an unattainable love or someone important who's drifted apart or gone away, thanking what remains—the memory of them as seen from behind—even while it brings sorrow and inability to connect or reach out.
