Description：Li Changshun (played by Zhang Guoqiang) was born and raised by the Yalu River. One day, the land he loved deeply and the village on which he depended for survival were bombed by U.S. military aircraft. The quiet village in the past suddenly fell into a sea of fire. The lives of the fathers and villagers were as fragile as grass, and they were annihilated in an instant. Li Changshun, who witnessed all this, was filled with grief and indignation. He joined the volunteers to serve the country on the front line and avenge his fellow villagers. Li Changshun and his comrades advanced and retreated together, tasted all the sufferings of the world, and also went through countless critical moments where their lives were hanging on the line. They forged an extremely deep friendship with each other. However, the ruthless war still took them away from Li Changshun one after another. With hatred in his heart, Li Changshun is always the first to stand up and fight on the front line. He used his sweat and blood to build a brilliant new China.
