Recently I read the book "How Steel Was Tempered" and it moved me deeply. The protagonist in the book, Paul Korchagin, gradually grew from a student to a fighter fighting for freedom in the flames of war. In his long journey of growth, there were inevitably some setbacks and difficulties, but he did not give in. I remember one time during the battle, Paul rushed forward regardless of his own safety. At this time, a grenade fragment pierced his body. He was in unbearable pain and fainted on the spot. While he was recovering from his injuries, his mother felt very sad. He was anxious, but he always had a smile on his face, as if he had never been hurt. Paul was dedicated to the country, even if one eye was blinded, he still would not give up. Is his optimistic and indomitable spirit something we should learn from? In our daily life, we should not give up because of a small setback. We should also learn from Paul and his perseverance. After reading this book, the plot inside was unforgettable for a long time, and the protagonist Paul was also engraved in my heart.
