Xu Junchuan is a dependable, hardworking veterinarian in town. For 50 yuan per pig, he provides a comprehensive service package that includes medical records, scheduled vaccinations, routine inspections of livestock pens, and 24-hour emergency visits. The newcomer, Zhao Qiming, undercuts him by charging just 30 yuan and spreads rumors that Xu Junchuan is making exorbitant profits. Tempted by the lower price, local farmers, led by Boss Du, demand refunds for the price difference and insist on collectively switching veterinarians. Facing pressure from everyone, Xu Junchuan produces his extensive medical records and emergency visit logs to defend his pricing, refusing to lower his fees or compromise. Zhao Qiming then tries to win everyone over with attractive offers, including feed on credit and guaranteed purchase prices for pigs. But behind these seemingly generous benefits lies a hidden scheme.
