The story of Chen Tang, a water-town youth, returning home to save his father and counter fishmonger Gao Guanghai. To cheaply swallow up the Chen family's fish ponds, Gao Guanghai blocked the waterway with large boats and blocked the pond ridges with vehicle convoys, forcing Chen's father to go into the water at night to pry the floodgate, where he was injured. Chen Tang calmly responded by calling the police to keep evidence, clearing waterways, repairing new roads, and gathering evidence to counter his opponent, securing an order of 960,000. Gao Guanghai raised prices to snatch goods and privately built a steel bridge, causing rusty water to pollute the fish ponds. Chen Tang settled accounts publicly with evidence, and the police ruled that he compensate 184,000 and suspend business for half a year. Gao Guanghai conceded defeat and cleared the way, and the fish ponds became clear again.
