In the late Qing Dynasty in Lingnan, Jiang Yuan, the son of a tenant farmer, was born in Jiangwukeng. Since childhood, he has been oppressed by landlord Jiang Shouzheng's exorbitant rents, and the fire of resistance was planted in hunger and humiliation. With the rise of the Peasant Movement, he joined the peasant army. He fought bloody battles against encirclement and suppression but suffered heavy losses. He fled to Southeast Asia and became a coolie. When the Anti-Japanese War broke out, he led the overseas Chinese engineering team and rushed to transport anti-war supplies on the Burma Highway. When the civil war broke out, he traveled to Southeast Asia to support the liberation cause. His home and country were separated, and he missed each other terribly. The red flag of liberation rolled over southern Xinjiang, but he was unable to settle his old grievances and dared not return home. During thirty years of war, he endured the disasters of his family and country with his single-minded courage, and kept his original intention intact. In the end, the red flag reflects his original intention. Can he fulfill his long-cherished wish and stay with his family in his homeland?
