Memories of childhood become more and more blurry with age, but as you experience more, you will feel that the innocence of childhood can never be returned. I would like to write this book to commemorate my passing childhood... In addition, most of this book also expresses my thoughts and feelings about the great rivers and mountains of the motherland and traditional culture, and the Chinese roots in the children's fun of mountains and rivers! I wanted to use this as the title, but I couldn't change the title. Every story is heartfelt and heartfelt. I will always be deeply proud of the treasures of my motherland, and also proud of being a Chinese!
