深海再深不及人心但我信你黑夜再黑不及人心但我懂你
[shēn hăi zài shēn bù jí rén xīn dàn wŏ xìn nĭ hēi yè zài hēi bù jí rén xīn dàn wŏ dŏng nĭ]
The phrase 'Deep seas can never match the depth of human hearts, but I trust you; dark nights can never be darker than human hearts, but I understand you.' It symbolizes deep faith and understanding in a relationship, suggesting that no matter how complex and unpredictable human emotions are, there's a profound mutual trust and understanding between two individuals.
