深爱是胸口有雷霆万钧唇齿之间只有云淡风轻
[shēn ài shì xiōng kŏu yŏu léi tíng wàn jūn chún chĭ zhī jiān zhĭ yŏu yún dàn fēng qīng]
It poetically interprets as: 'Deep love is to feel intense feelings surging in one’s heart, but expressing them mildly as light clouds and gentle breeze'. It represents a deep-seated love for someone or something with passion kept inside rather than loudly voiced outside. It is a sign of deep affection held privately.
