I read one book.
The books name is kinoinochi kinokokoro.
Writer wrote not only the trees quantify but also wrote about human education.
I thought present Japans education should be revised upward.
When people read this book ,many will think why quantify of tree and human education are correlated.
You will understand if  you read this book!
