那些年被记忆抹去
[nèi xiē nián bèi jì yì mŏ qù]
'Those years erased by memories', means some past times and experiences are fading away, almost being wiped out from recollection. This might reflect that the owner values certain periods in the past which perhaps contain stories of love, friendship, etc., yet these have all gradually been forgotten or even deliberately forgotten with the passage of time.
