光年之后的旧知己流年之后的旧友人
[guāng nián zhī hòu de jiù zhī jĭ liú nián zhī hòu de jiù yŏu rén]
This name reflects nostalgia and the passage of time. It conveys a feeling of reminiscence for old friends from a long time ago, possibly emphasizing that no matter how much time has passed (light years later, years after), these friendships still hold significance in the person's heart.
