最美不过湛蓝深海
[zuì mĕi bù guò zhàn lán shēn hăi]
'Nothing is more beautiful than the dark blue deep sea' emphasizes an admiration for something profoundly attractive yet perhaps distant or unreachable—like a vast, deep sea whose mystery and depth add layers to its allure. It can refer metaphorically to someone who finds immense beauty in solitude or depth.
