This is a realistic novel, everything really happened around me, and the real reality is more cruel than the novel, and people are more changeable and tough than in the novel. I am not praising anyone or belittling anyone, because there are no absolute good people and bad people in the world, only people who have done good things and people who have done bad things. Human thoughts are so complicated that they cannot be unified. I just like the saying "You can not love, but please don't hurt." Like animals, humans live in a competitive world where the strong eat the weak. The difference is that there are legal protections that are more civilized. Therefore, people should be kind and protect themselves at the same time, and maintain a good attitude when encountering difficulties and injustices. The world of adults is not easy. People should see their own abilities and character more clearly through continuous experience, improve their wisdom, understand the various principles of life earlier, understand the pain and joy of life, and live optimistically. "If you are poor, you can be good for yourself, and if you are rich, you can help the world." When we are trapped in a whirlpool and cannot escape the clutches of bad luck, we feel so wronged and unfair. If the theory of cause and effect is accurate, "the way of heaven will make up for the loss, and the way of man will make up for the loss." I hope my words can accompany your loneliness, and I hope my story can open up your wisdom!
