Zhao Qing, the CEO of Yazhu, secretly helps her fellow villager Sun Guifang, only for Sun to pass off moldy frozen duck as braised goose to make a profit and publicly extort Zhao Qing. Disheartened, Zhao Qing ends their partnership and demands repayment of 300,000 yuan in rent. She then meets Li Cuihong, an honest lunchbox vendor, and wholeheartedly supports her catering business. Resentful, Sun Guifang joins forces with her son to repeatedly file malicious complaints, plant an undercover employee to frame Li Cuihong, and spread false rumors to smear her reputation. Zhao Qing exposes every scheme with solid evidence. After the Sun family sells spoiled ingredients and causes mass food poisoning among company employees, their wrongdoing is fully exposed. They receive severe penalties and are blacklisted by the industry. Meanwhile, Li Cuihong remains true to her principles in the food business, expands her stores, and opens a charity meal station, earning everyone's respect through her honest work.
