Lunchbox vendor Zhou Jianguo insists on using good ingredients, pricing his lunchboxes at 12 yuan. Facing the impact of a competing 8-year low price and public misunderstanding, he always adheres to the food safety baseline, and never sells overnight spoiled food. After a collective food poisoning incident occurred at the construction site, the truth came to light. Zhou Jianguo won recognition through conscientious management, and also used his experience to tell everyone that doing business cannot only pursue low prices, and integrity and food safety are more important than profit.
