At the entrance of the construction site, Lao Gen has sold 15-yuan freshly-fried egg fried rice for fifteen years as usual, using fresh rice and fresh eggs with a conscientious ladle. His apprentice, Xiao Lei, to grab business, used 9.9-yuan stale rice, broken eggs, heavy oil and heavy sauce, and even spoiled ingredients, causing the workers to suffer collective poisoning and the project to stall. After the incident, Xiao Lei was investigated, and Lao Gen was invited back by the project department. He set down the rule: only 250 portions a day, 15 yuan, no price increase, no cutting corners. The workers queued up to apologize, and with a pot of clean rice, Lao Gen guarded his conscience and also stabilized the people's hearts.
