Master mechanic Chen Guodong earns a monthly salary of 15,000, handing over his entire salary for five years of marriage, yet he couldn't even afford a 6-yuan beef noodle soup, prompting him to decide on a divorce. His ex-wife colluded with her lover, the general manager of Hengtong Region, and store manager Qin Weidong took the opportunity to swap parts to frame him, firing him and blacklisting him across the entire industry. Chen Guodong took his apprentice to set up a car repair stall in the urban village damai area, strictly adhering to the rule of keeping evidence and writing work orders. Gathering documents and evidence, he tore open the corporate black market operation of reselling scrapped parts right in labor arbitration, bringing down a crowd of responsible parties. After weathering the storm, he partnered to open a shop, stayed true to his original intention of repairing cars, and finally earned his own dignity and life.
