人心不如出岁月不如故
[rén xīn bù rú chū suì yuè bù rú gù]
Hearts not compared while time passes by, so nothing is better than old acquaintances or old times. The internet user sighs for nostalgia, meaning that new people/new relations don't have the same value/weight as past times with the old, conveying longing for old memories or good relationships
