Community workers stuck to their posts, registering information and delivering supplies to weave a tight-knit grassroots protective network. Countless ordinary people voluntarily stayed at home, supporting the anti-pandemic efforts with their simple yet extraordinary actions.From the rapid construction of makeshift hospitals to the successful development of vaccines, every breakthrough was forged with the sweat of innumerable people. Tiny sparks converged into a river of stars. In this war without gunsmoke, unity and perseverance emerged as the most powerful weapons, ensuring that we would eventually greet the arrival of spring—when flowers bloom and warmth returns.
