曾经已是曾经过去早已过去
[céng jīng yĭ shì céng jīng guò qù zăo yĭ guò qù]
'What Has Happened Belongs To The Past.' These Chinese words are meant to express someone's attitude toward past memories: emphasizing they have come to terms with the past, as everything that happened has become a part of history, reflecting on not wanting to reminisce too much on former glory or regrets.
