Lin Daqiang spends 30,000 yuan of his own money to build an underground, leak-proof irrigation canal for the entire village. Liu Dalai, a villager, lies down to block construction and extort 20,000 yuan in so-called passage fees. Lin Daqiang would rather spend an extra 8,000 yuan blasting through rocks to reroute the canal, leaving the Liu family's fields as the only area cut off from water. When a severe drought hits, Liu Dalai secretly drills into the pipeline at midnight to steal water, causing it to burst, and is forced to pay the emergency repair costs in front of everyone. He then tries to save money by hiring a fraudster to dig a fake well, only to burn out a large water pump. After all his schemes, he loses his entire fortune and nearly suffers a complete crop failure. Finally, his son returns to the village in a fury, forces Liu Dalai to publicly admit his wrongdoing over the village loudspeaker, and pays the outstanding 3,000 yuan water bill himself, reflecting: "Only when your heart isn't greedy does the water taste sweet."
