想你想到天荒地老爱你爱到海枯石烂
[xiăng nĭ xiăng dào tiān huāng dì lăo ài nĭ ài dào hăi kū shí làn]
In a sense, this nickname expresses undying love with the meaning of loving someone endlessly until heaven becomes desolate, earth old, seas drain dry, and stones decay. Such phrases emphasize the intensity of one's feelings for another.
