Lin Xia is clear-headed, rational, and upholds fairness. When buying braised food at the farmers' market, she discovers that stallholder Fatty Wang has made mistakes of short-weighting and passing off inferior goods due to operating pressure, and she rationally points it out and defends her rights according to regulations. In a moment of confusion, Fatty Wang colludes with butcher Zhao to engage in improper behaviors such as monopolizing supply and maliciously speculating. Facing deliberate harassment, Lin Xia is neither humble nor arrogant, relying on retained evidence, connecting with regular supply sources, and relying on the law and regulatory power to resolve the crisis, both safeguarding her own rights and interests and guiding Fatty Wang to face the problem directly.
