In Nianzi Mountain, Heilongjiang, Hua'an Factory has experienced ups and downs over the past 50 years, hiding the hottest years and human feelings of a generation of military industry.
Chen Shanhe, who has grown from an apprentice to the most capable buyer in the factory's supply department, has a sharp mind, understands people's feelings, and sticks to the bottom line. In an era of material shortages and turbulent changes, he holds the lifeblood of scarce materials, but he has walked a tightrope between public and private, love and reason, profit and justice throughout his life. He traveled around to solve problems in factories, supported his neighbors, faced ups and downs in workplace clandestine battles and the tide of the times, never crossed the line in the face of temptation, and stuck to his conscience in the midst of turmoil.
