A five-year company veteran, he single-handedly propped up the core technology. His year-end bonus was zero, performance rating D, and at the annual gala he didn't even deserve to have his name mentioned. Others got 120,000, 80,000, 50,000, but he got 0 yuan, and then he calmly handed in his resignation letter. After he left, the company's biggest client canceled their order, the system crashed, and market value shrank. Those who stole his credit finally understood that the person they stepped on under their feet was the only load-bearing wall in the entire building. And he, taking his own technology and team, opened a new company and signed a multi-million contract.
