This document is only for all those in the 21st century who have gone through many vicissitudes of life under the ravages of reality and it is not easy to love. Sprinkle the troubled water of youth into the torrent of years behind your head. After leaving the school gate, will we be separated from each other or will we be separated from each other? After all, he can't escape the world of Yanhuang Chiyou. Why pretend to be confused and let yourself be confused and deceive yourself that you really deserve to be sad? No one can change, and those who stick to the rules are wrong. I have made a decision and will not look back even if I hit a wall. I am just afraid that not being confused now is just trying to be strong. Men should not be sad, but reality forces him to hesitate. I am not afraid of working hard, but I am also afraid of the final despair.
