I hope this article is a happy fruit for me and us. It's warm, funny, and slightly autobiographical. I wrote this book to record the warm, fun, and sweet things in my life. After all, no one knows when we will grow up, get old, and forget. In this book, there are weird classmates, funny teachers, startling glances, and moments that move you to tears. I stood under the big tree of youth and gently picked up these precious petals. I hope it can make the corners of your mouth curl up quietly. This is the greatest meaning of this book.
