吵吵闹闹从不言离弃磕磕绊绊从不言分离
[chăo chăo nào nào cóng bù yán lí qì kē kē bàn bàn cóng bù yán fēn lí]
Means that even when we quarrel loudly or have conflicts and difficulties ('trip over'), we never say parting words. This emphasizes resilience within a relationship no matter how many disputes and disagreements there are. It highlights unwavering commitment despite all obstacles and differences.
