For three years, Pei Zhen, a technical backbone who gave silent dedication, had his year-end bonus cleared to zero, while the colleague who stole the credit took away five hundred thousand. He made no fuss and resigned peacefully. At midnight, the company servers suffered a sudden breakdown, and the entire staff was helpless, with the core architecture in his hands alone. The CEO personally came to his door for help, and disregarding past grievances he fixed the system in half an hour, yet still chose to leave. People with real capability never prove themselves through arguments, and those who work down-to-earth can shine wherever they go.
