不吵不闹看你幸福
[bù chăo bù nào kàn nĭ xìng fú]
Not making any noise watching your happiness. Reflects quietly wishing the best for the object of love, even from afar. Implies letting go gracefully without confrontation or dispute after a relationship ends, hoping the ex-partner lives happily henceforth, showcasing a mature yet slightly melancholy attitude towards failed relationships.
