In 1937, when the Marco Polo Bridge cannon was fired, Lin Wenxuan, a teacher in Yulin Town in North China, Zhao Tiechui, the son of an Orion, and Su Wanting, the daughter of a squire, stepped forward in the critical situation of destroying their country and their family. From spontaneous resistance to joining the Eighth Route Army, they experienced bloody battles such as the explosion of poison gas depots, anti-mopping up struggles, and county liberation. They witnessed the sacrifice of their loved ones and the shattering of mountains and rivers. In the end, they grew from ordinary people to staunch revolutionaries in the flames of war. The work uses delicate brushstrokes to show the unyielding backbone of the Chinese nation, and pays tribute to those ordinary people who used their lives to ignite hope in the darkest moments.
