When I Joined the Company for the Second Time, I Became the Ceo's Mentor.

Sixty-year-old Shen Qingshan retired as the financial director of the group. He thought that the stage of life had come to an end. Under his son's arrangement, he concealed his past and, as a "logistics consultant," entered Zhiyun Technology, an Internet unicorn full of young hormones where his son worked. Here, he became the talk of the tea room: an "old antique" who played with a mahogany abacus and wrote notes in an Excel sheet. The arrogant young CEO Lu Chenzhou regarded him as a "connected person" who needed to be appeased and placed him in a corner. A storm is coming. A fatal flaw appears in the big data model that the company is proud of, which may lead to huge losses. When the room full of technical elites were helpless against the flashing code, Shen Qingshan silently pulled up the account books from thirty years ago. Without a single line of code, and with only the most basic double-entry accounting method and a logical Excel table, he deduced backwards like a detective and accurately identified key variables that were ignored by the AI ​​model but originated from human nature. At that moment, the world was silent. Lu Chenzhou's arrogance began to collapse in his shocked eyes. Since then, the corner office has become the anchor of this fast-running technology company. Shen Qingshan used simple principles about human nature, cycles and risks that he had honed over half a century to calibrate the direction of this young beast. From cracking business scams, rallying disorganized teams, to dealing with policy black swans, and guarding the soul of the company, he has used the wisdom of the "old world" to solve the most difficult problems of the "new world" time and time again.
