This book is the representative work of Tetsuko Kuroyanagi, a famous Japanese writer and TV presenter, Little Doudou by the Window. This book tells a true story of the author in primary school. Education is a very complicated and responsible job. Educators should understand children, help them, guide them, respect their nature and adopt educational methods suitable for their different personalities. It is a good book worth reading by educators. Principal Kobayashi, the protagonist in the book, founded the "Ba Xue Yuan". Educational activities such as rooted school gates, tram classrooms, lunch with mountains and seas, camping and swimming adventures left unforgettable memories for the children who studied and lived there. Mr. Sousaku Kobayashi has no utilitarianism in running a school. He cares about children and pays attention to their growth and progress. He has always paid attention to protecting children's childlike innocence, giving children self-esteem and creating conditions for each child to express himself. This book tells us how to educate people: what is the essence or true face of education? I think it may be that Mr. Kobayashi tried his best to protect the children's upward, kind and kind "early life" character. It is teacher Kobayashi's expectation and patience that enables every child who lives and studies in the "Ba Xue Yuan" to grow up healthily and achieve something in adulthood. Education is a slow art, which requires educators to be slow in mind and ability. After reading this book, I feel that in our country, in today's era, there is an urgent need for some principals and educators like Sousaku Kobayashi to run schools, trying to dilute the idea of running schools for quick success and instant benefit in today's society. I also hope that our teachers can get some inspiration from the book, deeply reflect on our educational behavior, be more patient, encourage and give more confidence to children, so that children can develop freely in a free, relaxed and harmonious atmosphere.
