海上无比平静心里无比荡漾
[hăi shàng wú bĭ píng jìng xīn lĭ wú bĭ dàng yàng]
While everything looks peaceful at sea, there's turmoil inside. This expresses feeling internal agitation despite an outward appearance of calmness. A metaphor often used when one is profoundly touched emotionally by someone or something.
