淡忘已久
[dàn wàng yĭ jiŭ]
'Dan Wang Yi Jiu', in English means 'Almost Forgotten'. It expresses that many memories, events or even emotions gradually fade out from memory with the passage of time. There are always people, affairs or feelings, no matter how deeply they have been etched in one's mind, there will come a day when one starts to become a bit fuzzy about them, until almost forgetting them.
