我怀念的是无话不说我怀念的是一起走过
[wŏ huái niàn de shì wú huà bù shuō wŏ huái niàn de shì yī qĭ zŏu guò]
This translates to 'What I miss is talking without restraint; what I cherish is having walked together.' It expresses nostalgia for close relationships where communication was open and honest, and there's fondness for shared experiences and past memories.
