In 1994, Li Wanyue, the chief technical engineer of the Qinghe County Cotton Textile Factory, took her daughter Lin Xiaoyu to register for a key municipal primary school, where she came into conflict with Chen Rong, a factory employee who cut in line. During the dispute, she was shocked to discover that Chen Rong was actually her husband Lin Jianguo's extramarital lover. Not only did the two have a son together outside of marriage, but they had also long occupied the school district public housing assigned to her based on her technical achievements. After Lin Jianguo rushed over and openly favored Chen Rong to save face, Li Wanyue grew completely cold-hearted and resolutely divorced him. Once Lin Jianguo's corruption and embezzlement were exposed, he was thoroughly discredited and ruined. Li Wanyue gave up her iron rice bowl to start her own business, opened a sewing workshop backed by her superb technical skills, teamed up with technical backbone Gu Heng to fight side by side, and ultimately established a garment processing factory, living out an independent life.
