阳光透过指缝刺痛眼眸
[yáng guāng tòu guò zhĭ féng cì tòng yăn móu]
Sunlight passing through fingers hurts the eyes – it's an expression using sunlight to metaphorically represent moments or things that bring discomfort, but also can imply fleeting beauty or melancholic nostalgia as the sun rays pass through fingers quickly and might not be held onto easily.
