等你等到天荒地老恋你恋到海枯石烂
[dĕng nĭ dĕng dào tiān huāng dì lăo liàn nĭ liàn dào hăi kū shí làn]
Meaning 'wait for you until the end of time and love you until seas dry up and stones decay', expressing eternal devotion and unwavering loyalty in love—an everlasting love that doesn't care about time and change.
