It is difficult to recover the original song from the past.

The past is hard to undo. The original singer was Feng Feifei. Don't indulge in the empty dream of spring, which is gone forever. Don't revel in the beauty of dreams, because when you wake up, your dreams will be broken. Can only recall the past, it is difficult to recover. Unforgettable Memories is a song sung by Feng Feifei, written by Feng and composed by Feng. It is included in the album Love Story-Lonely Voice.
