时光薄了执着时光厚了怀念
[shí guāng bó le zhí zhe shí guāng hòu le huái niàn]
Translated roughly, this phrase reads as 'Time Thins Out Perseverance Yet Fattens Nostalgia.' It reflects a profound understanding of how time changes our feelings: we may become less obstinate over time while our longing or remembrance for past days grows stronger as they gradually move further away.
