承诺的海枯石烂允诺的天长地久
[chéng nuò de hăi kū shí làn yŭn nuò de tiān zhăng dì jiŭ]
This online name means 'promised until the sea runs dry and the rocks crumble, promised forever.' It is derived from classical Chinese romantic expressions promising eternal love, where 'sea runs dry and rocks crumble' symbolizes an unimaginably long time or unchangeable things.
