海誓山盟不過如此分分合合终未到老
[hăi shì shān méng bù guò rú cĭ fēn fēn hé hé zhōng wèi dào lăo]
Roughly translates to 'Oaths sworn beside the sea and mountains turn out to be just coming together and apart again before getting old.' This line expresses disillusionment with love vows, reflecting on how intense promises of forever may still end in separations.
