From the front desk to the project manager, Xu Zhinan insisted on "working side by side without crossing lines" and used executable methods to break through the workplace: parallel plans to stabilize the first firefighting, comparative experiments to obtain the budget, and public interfaces to resolve public opinion; when she was about to be promoted step by step, a "black swan" stopped the project, reputation backfired, and she fell into a trough. Shen Jixing chose to accompany her to restart with resources and methods instead of making decisions for her - small order verification, rules first, and the two got close to each other in the boundary. After regrouping, they founded a new company, bid on the same stage with competing products and old employers, and attacked key projects with "user co-creation + third-party endorsement". Gu Ye and Lin Tang also lit up each other side by side.
