Lin Wanzhao is the most inconspicuous screw in the Red Star Machinery Factory. The good news: She is a worker's child with a good background. She followed her father's footsteps and joined a large factory. She holds an iron rice bowl in her hand and her monthly salary is thirty-eight and a half yuan. She will never starve to death.

For three days and three nights, when the machine tool roared steadily again, the entire workshop was silent. Since then, there has been a legend in the Red Star Factory - the little girl named Lin Wanzhao can know where the "disease" of the machine is by touching it with her eyes closed. Old stubborn workshop director: Hey, Xiaolin, you will take the lead in this technological innovation project.

The factory next door pays a high salary to poach people: forest workers, come to our place and give you a two-bedroom apartment! And that handsome young man who always silently helped her with her hands and tightened screws,
