This book is dedicated to my good friend the Forestry Ministry. When I was a freshman in college, my good friend Ye Sheng committed suicide. I still don't know the reason. Although everyone said he did it for a girl and a relationship, I still can't believe it, and I don't want to believe it. He is still so vivid in my memory. When we were in school together, he was always happy to tell me about his love and the girls he liked. He is gone. I hope he will become a free and easy poet in his next life and experience a beautiful, simple, clean and innocent love. Everyone knows there is no if, but Ye Sheng, I am blaming myself. If we could care more about you and comfort you, you might not have taken this last road. For such a sunny person like you, a girl will definitely be happy because of you in the future. You should live well.
