Chen Miaomiao's career was completely changed by a public humiliation by airborne manager Lu Jingshen. She was forced to start the supplementary mode, but found that there seemed to be some kind of "cultivation" hidden behind Lu Jingshen's harshness. Chen Miaomiao replaced VLOOKUP with INDEX+MATCH and completed the dynamic Kanban board with PowerBI. The harder she worked, the more complicated Lu Jingshen's eyes became. When she used data to expose deep problems in the company's operations, he did not praise her, but silently handed her a glass of warm water. "Don't push yourself too hard." Lu Jingshen (whispered). Her heart trembled. Did he already know the company's secrets? Was he being strict back then to protect her or to test her? She was successfully promoted to head of data analysis, and the two became indispensable workplace partners. But that "complicated" look is always in suspense: is it appreciation? Is it guilt? Or, transcending the boundaries between superiors and subordinates? The company's survival crisis is approaching. Chen Miaomiao needs data, and Lu Jingshen may need her.
