In my memory, school days are very happy days. Everything that happens in school brings us joy and tears, teaches us how to grow, and guides us how to move forward. At that time, we loved to dream, and the dreams were colorful; at that time, we loved to laugh, and the laughter was hearty and pure; at that time, we were troubled, but our troubles can be forgotten. We were here then, where were you? I would like to dedicate this article to those of us who have gone through our youth or to you who are going through it. Let each of us say thank you for the time! Have good intentions and never forget your original intention. Slow down occasionally and look up. The sun is shining brightly and the sky is clear, isn't it? Youth is a song, and youth is an everlasting song.
