忧伤拂过天空的脸
[yōu shāng fú guò tiān kōng de liăn]
Translated literally, it reads 'sadness brushes across the sky's face.' This paints a vivid yet melancholic picture of feelings of sorrow as vast and limitless as the sky. It represents a deep, pervasive sadness intertwined with the boundlessness of existence.
