This production contains AI-assisted content, and its story is a fictional dramatization. Chen Li, a food delivery rider, feels inferior because he never completed junior high school. Encouraged by Teacher Wu from the community night school's electrical engineering class, he signs up for a skills competition and begins training in the residential complex's maintenance room under the property management supervisor, Old Zhou. Old Zhou strictly enforces safety regulations, making Chen Li start with the smallest details, from testing for electrical current and putting up warning tags to returning tools to their proper places. Chen Li gradually overcomes his fear of spending money, embarrassment, and habit of rushing. At the competition, he scores 91 points in the practical test with no deductions for procedural errors, wins the District Outstanding Practical Skills Award, obtains his low-voltage electrician certification, and is recommended for a transfer to a property management technician position.
