a boy in rags, dying in a crowded station, is approaching the end of his short life at the age of 14. This is Japan one month after the defeat. In a trance, the teenager saw his dead sister and the summer full of fireflies. At that time, my brother and sister were happy. Small iron boxes filled with candy, fireflies flying all over the sky, my brother holding my sister's hand running at night and my sister's silvery laughter all became the merciless foreshadowing of the upcoming tragedy. The air raid began, and my mother died suddenly in the bombing. In the face of this sudden blow, all my brother could do was hide the news of my mother's death from my younger sister. In the empty square, my brother worked hard to perform the horizontal bar for his sister who was crying for her mother. In the sunset, two thin figures looked so thin. Perhaps, at that moment, my brother tried to carry all his sadness and decided to hold a clear sky for his sister on the chaotic ruins. Brothers and sisters took refuge in their relatives. However, the war alienated their relatives, and the lack of material made people indifferent to each other. More and more dirty eyes and less and less rice in the bowl clearly show that they must leave. My brother finally decided to move away with my sister and build a home of his own. However, when he left happily singing, could he have expected their irreversible tragic fate because of the war? Fireflies fly again, but the bad luck of brother and sister keeps coming. Hunger and disease have become the biggest problems that plague them. In order to make my sister stop being hungry, my brother has to steal it, and when the plane is bombed, whenever he finds something to eat in the family he fled, he will be extremely excited. The film has given this life more pen and ink. Abandoned homeland and desolate Yuan Ye, every detail looks so real, bleak and cruel, and indifference and warmth coexist. (Soundtrack: My brother was caught stealing. After being beaten, he was sent to the police station. The police were very considerate of his situation and released him. ) In the dark abandoned cave, my brother caught the fireflies into the mosquito net, and the fireflies flying all over the sky were clearly extinguished in the sultry night in summer. My brother clung to his sleeping sister for fear that he would lose it once he let go. At the age of 14, he didn't know that war itself meant loss. The life of fireflies is only one night, and everything is gone in the summer breeze. (Soundtrack: My sister gently buried the small body of fireflies last night in her own grave and said to her brother, "I miss my mother very much, and my mother is in the grave." My brother stared at my sister in surprise. )
