The Children Must Not Cry is a book that I picked from the bottom of my heart to ensure peace and stability in the world. I have not experienced a lot, but I have seen or heard the problems that people encounter in the struggle for peace, through wars, conflicts, and other problems. The saddest part of it is the life of children; they are vulnerable and need help to survive. I wrote this book not to cause problems but to make peace between people of all areas. In life, it is hard when certain things happened, but truthfulness, patience, and hard work are the weapons to fight evil. It is a book that I wrote not to make people sad but to give courage to the world for peace. This book may contain some stress, flashing images or words of sympathy, and I am very sorry for any inconvenience. Life is full of challenges that must be overcome through good to achieve good.
