十年之前不相离十年之后久不见
[shí nián zhī qián bù xiāng lí shí nián zhī hòu jiŭ bù jiàn]
Translating roughly as “won’t leave within ten years before (the present), but don't meet much in the ten after.” The person reminisces the past where relationships lasted long, whereas nowadays there’s barely interaction after ten-year gap, reflecting on a sense of distance brought by the flow of time and change of relationships
