五十米蔚蓝
[wŭ shí mĭ yù lán]
'Fifty Meters of Blue' evokes a visual image of a large stretch of blue, like the ocean or sky viewed at a distance of fifty meters. It symbolizes tranquility, vastness, and possibly a metaphorical escape to somewhere beautiful yet unreachable. It also captures a mood of longing or reflection on distant ideals.
