Lin Chen's auto repair shop faces a strike by four senior mechanics who demand higher pay and refuse to work. He decisively dismisses them and overhauls the rules, replacing traditional inspection pits with a fully transparent, intelligent workshop. Using standardized, data-driven procedures instead of relying on the skills of so-called veteran mechanics, he transforms the business. When rivals frame him, he fights back with a traceability system and cloud-based reports, ultimately building an auto repair empire worth hundreds of billions.
