According to the query of Baidu Library, the sentence "The past is not turned back, and the rest of my life is not settled" means that the past is over, and I won't look back. In the next life, I will treat myself well and live a happy life. Cherish the present life, don't die in the past memories, but also look forward to the future. People have to go through many things in their life. If they just worry about the past and feel sorry for the past, they will never find the present beautiful and feel that their life is better than before. This is a question of human nature. If we always look back at people and things in the past, we will find that we are not doing well now. We should remind ourselves that we should look forward in life and don't always look back. The past is precious, let it exist in our hearts.
