海枯石烂不过仅此而已
[hăi kū shí làn bù guò jĭn cĭ ér yĭ]
'Even if seas run dry and rocks decay, it's nothing more than this.' In Chinese literature and culture, 'seas running dry and rocks decaying' is synonymous with eternality or an unchangeable fact. This name could refer to the fragility or brevity of all things, including promises and vows, suggesting some kind of disappointment.
