In 1962, the fighting hero Hong An was seriously injured on the battlefield in the southwest. His comrade Yang Jianguo sacrificed his life to save him. On his deathbed, he asked his orphaned mother and pension. Hong An was demobilized and returned to No. 95 Courtyard in Sijiu City, where he was appointed chief of the security section of the steel rolling mill and deputy director of the police station. As soon as she returned to the hospital, she saw that Aunt Yang was being robbed by the Jia and Zhang family for preparing "road meat" for her son. The three uncles also favored the Jia and Zhang family. In order to fulfill his promise to his brothers, Hong An, who was seriously injured and had not recovered, stepped forward and vowed to seek justice for the families of the martyrs.
