给不了他幸福就放开他的手
[jĭ bù le tā xìng fú jiù fàng kāi tā de shŏu]
'Let Him Go if You Cannot Give Him Happiness'. This reflects an unselfish viewpoint where someone lets their loved one go because they can't ensure happiness for them anymore. It embodies a desire for someone’s best interest beyond one's capacity to provide.
