Zhang Yu worked as a mechanic in a factory for eight years, only to be humiliated and have his salary docked by the connected supervisor Li Xin, and even publicly awarded the "Master Slackers Award." Outraged, he resigned and joined Ruike Automation Company, breaking through technical bottlenecks with his solid practical experience to become the R&D manager. The original factory fell into crisis due to chaotic management, and the chairman personally invited Zhang Yu back to serve as an honorary consultant. He ultimately established a technology heritage studio to cultivate newcomers and became an industry benchmark.
