In the drawer in my grandfather's room, there is an old, yellowed booklet wrapped in blue cloth. It is an incomplete notebook. The words on it were no longer legible 70 years ago, but my grandfather has always kept them well, because it records things and names that he will never forget in his life.
If you are too young to understand those meaningful stories, one day you will look back and understand that the protagonists of the story had many opportunities to give up, but they did not. They decided to move forward bravely because they held a belief that there must be something in this world worthy of their fight to the end.
