On the eve of Qingming, two rural roasted pig shops engaged in a price war. Zhou's shop used low prices to grab a large number of orders, mixing in frozen goods and compressing procedures to rush production. Chen's shop persisted in the quality of fresh pork, preferring to shoulder losses rather than lower standards. During Qingming ancestor worship, Zhou's roasted pigs successively broke out with quality accidents, triggering a collective rights protection by villagers. Through the market supervision department's investigation to clarify the original cause, Zhou Guoliang paid the price for his profit-driven mistakes, and the villagers also reflected on the problem of blindly following the crowd. Chen Jiahao won long-term trust with his solid reputation.
