In the book, the author recreates the image of the generation of Hanoi students – intellectuals entering the battlefield with light backpacks but full of books, music and student memories. The contrast between the fierce bombs and the romantic and pure beauty of the boys in their twenties becomes even more prominent. It is the cultural and educational background that has created their own way of thinking: sensitive to beauty, rich in compassion, respectful of love and always keeping dignity even in the midst of bombs and bullets.
