Lu Qisheng once ended up hospitalized from exhaustion after covering her coworker Zheng Zixuan's shifts. When she was pressured to take over someone else's shift again during the Spring Festival, she resolutely refused. Unexpectedly, Zheng Zixuan left her post without permission, causing massive losses for the company, and even tried to pin the blame on Lu Qisheng. Armed with evidence, Lu exposed the lies and used her exceptional professional skills to rescue the company from crisis and turn its fortunes around. From an ordinary employee who was constantly ordered around to a supervisor capable of standing on her own, she not only achieved a remarkable career comeback but also challenged unreasonable overtime rules, earning respect in both her professional and personal life.
