唯有星空似海洋仅有海洋容星空
[wéi yŏu xīng kōng sì hăi yáng jĭn yŏu hăi yáng róng xīng kōng]
Expresses a profound admiration of both starry skies and oceans. Literally meaning, 'Only the starry sky resembles the ocean and only the ocean can contain the starry sky'. Metaphorically it's used to compare endless vastness between inner mind, dreams, and aspirations with the real-world boundaries around.
