On the wedding day of Chen Dashan in Tianwan Village, neighbor Zhao Guangcai held a grudge over an election and used a feces truck to block the road, forcing the Chen family to kowtow and pay compensation. The Chen family had previously made concessions by giving up their homestead land to widen the village road, only to be manipulated by the Zhao family. The Zhao family piled gravel at the door, causing Chen's father to suffer a myocardial infarction and vomit blood. Relying on approval documents, the Chen family reclaimed their homestead and built a septic tank to counterattack during Zhao Meng's wedding. Zhao Guangcai colluded with grain merchants to suppress grain prices and forged evidence to smear Chen Dashan's grain-selling platform. Chen Dashan and his wife collected evidence and led villagers to build their own grain-selling channels. The Zhao family misappropriated road-repair funds and cut off irrigation ditches to force the signing of an unfair contract; after their crimes were exposed, they were handled according to the law, villagers gained independent control over grain sales, and Chen Dashan and his wife harvested happiness.
