海不会不深我不会不爱天不会不蓝我不会不在
[hăi bù huì bù shēn wŏ bù huì bù ài tiān bù huì bù lán wŏ bù huì bù zài]
'The sea cannot be shallow, my love won't cease; the sky cannot turn gray, I'll never be absent.' This reflects an unwavering commitment and constancy in love. It compares love's depth and stability to nature's enduring characteristics, such as the ocean's depth and the sky's blueness.
