Maintenance master Lin Chuan overspent 40 yuan on a replacement part to secure a major order, only to be heavily fined 40,000 and stripped of his authority by the boss. The boss forced the use of inferior parts to cut costs, which drove all orders away and brought the company to the brink of bankruptcy. Lin Chuan indignantly switched jobs, using his core skills to sweep up major orders. When his former boss begged for mercy after going bankrupt and was rejected, Lin Chuan proved that sticking to the quality baseline is the ultimate trump card!
