海水蓝透人心
[hăi shuĭ lán tòu rén xīn]
'Ocean Blue Piercing the Heart' evokes imagery of vast blue seas, reflecting purity or depth as vast and incomprehensible as love or sadness. This signifies a deep, overwhelming, almost indescribable emotion affecting someone powerfully or profoundly, often linked with feelings about life, love, longing, or melancholy.
