Liu Fang, the logistics supervisor at a machinery factory, takes her husband and son out for a meal. When her husband simply asks for half a bowl of extra rice, the fast-food restaurant owner, Zhao Chunmei, publicly humiliates the family. Liu Fang does not argue or seek revenge. Instead, she gives 96 factory workers another option for ordering meals. To her surprise, Zhao Chunmei's orders plummet overnight! Unwilling to accept defeat, Zhao Chunmei lowers her prices to steal customers, cuts corners on ingredients, makes malicious reports, and even spreads rumors online. Her actions gradually drive her nine-year-old restaurant to the brink of ruin. Only when the restaurant's signboard is finally taken down does she realize that it was never half a bowl of rice that destroyed her business, but the trust and goodwill she had squandered with her own hands!
