抱不住太阳的深海留不住深海的太阳
[bào bù zhù tài yáng de shēn hăi liú bù zhù shēn hăi de tài yáng]
This is a metaphorical name suggesting the futility of holding onto something as unreachable and fleeting as the sun for the deep sea, or in other words, an unattainable desire or affection that cannot be kept. It evokes a feeling of longing for something unachievable.
