Raw material prices rose, and food stall owner Qi Zheng insisted on quality, raising the beef nang to eleven yuan; competitor Wan Qishan launched a low-price war, seizing customers and bulk orders by cutting corners and reducing materials, forcing Qi Zheng to move away from the old carport. Relocating to the Huique freight yard, Qi Zheng started from scratch, building a solid reputation among long-distance drivers based on strict standards of freshly baked, ingredient-rich, and breathable packaging. Meanwhile, Wan Qishan caused a collective food poisoning incident due to cutting corners, completely losing credibility and collapsing. Eventually, Qi Zheng was invited back to establish a standardized system, growing from a lone stall owner into an operator who guards the bottom line of quality—a single piece of nang reflecting human hearts.
