沧海有涯此爱无岸
[cāng hăi yŏu yá cĭ ài wú àn]
Translated as 'The Sea has Bounds but this Love Knows No Shores,' it expresses deep, boundless love. The sea is often used metaphorically for vastness, implying that while even the most expansive forces of nature have their limits, this love transcends all boundaries and continues infinitely.
