从前有个神话叫天荒地老从前有个笑话叫海枯石烂
[cóng qián yŏu gè shén huà jiào tiān huāng dì lăo cóng qián yŏu gè xiào huà jiào hăi kū shí làn]
Translated to mean 'once upon a time, there was a myth called eternal barrenness, and once upon a time, there was a joke that means till the seas run dry and stones crumble,' it signifies a tale beyond mortal time or endurance. The phrase describes an impossible eternity.
