小打小闹小幸福不打不闹不幸福
[xiăo dă xiăo nào xiăo xìng fú bù dă bù nào bù xìng fú]
Translated as 'Little fights, little happiness; no fights, no excitement', it describes the belief that a bit of friction or playful conflict can add spice and depth to a relationship. This indicates a nuanced understanding of human emotions—that perfect peace is nice but not necessarily fulfilling, and sometimes a little trouble or difference leads to more vivid moments.
