像海从不怀疑天的蓝像天从不怀疑海的美
[xiàng hăi cóng bù huái yí tiān de lán xiàng tiān cóng bù huái yí hăi de mĕi]
'Like the sea never doubts the sky's blue like the sky never doubts the sea's beauty.' It portrays a profound trust and admiration, akin to an unconditional understanding and appreciation between two entities.
