念旧如初
[niàn jiù rú chū]
'念' means remembrance; '旧' indicates the past, or old memories; '如初' means 'as if at the beginning.' The whole term conveys the idea of remembering things or people from the past just as fondly as when one first started cherishing them. It's about holding onto nostalgia for a particular time with deep affection, almost like reliving those days in memory.
