天涯海角我定追随你到老
[tiān yá hăi jiăo wŏ dìng zhuī suí nĭ dào lăo]
It means 'To the Ends of the Earth I Will Follow You Until Old Age'. This reflects devotion and commitment to following someone, come what may, through all life circumstances, even to far and remote locations where one reaches old age together with a loved one.
