One week of the year star is one period, and one period is twelve years. Twelve years is not a short time in a person's short life. For those who are in their youth, it may be the entire youth years. The ancients revered the twelve years as a cycle of reincarnation. The first change in every child's life is the day he enters elementary school. From that day on, he begins to try to contact people outside the family. Elementary school, junior high school, and high school complete a step in his growth. They have not been tortured by the secular world, but they are still the most innocent. These twelve years have been the most innocent and beautiful twelve years in their lives, and even the pain is glowing softly. Children who have graduated from high school are facing a new starting point in their lives. From now on, they have to travel far away to study, establish a career, and struggle. Twelve years is really like a reincarnation. I would like to write this article to record and commemorate the story of a girl for twelve years. You will always find your shadow in her story. I wish all the boys and girls who have just completed this century of growth, good luck in their future.
