This is a heart-warming story that happened in a university cafeteria. Lin Yuan used five yuan to protect the food and clothing of poor students, but was forced to make corrections due to the hypocritical reporting of the rich second generation. He fought back against absurdity in the ultimate way, letting selfish people taste the bitter consequences and letting bureaucracy reveal its true colors. After the turmoil, the Wuyuan Stall was upgraded and guarded. The once arrogant people awakened and grew up through hardships, and goodwill eventually became a prairie fire. A bowl of hot rice preserves the dignity of students, and more importantly, justice and warmth in the world; a storm reveals the complexity of human nature, and witnesses the power of perseverance and growth, allowing the goodwill and justice in the campus fireworks to grow forever.
