The protagonist returns to the resource-scarce 1980s, armed with knowledge of future development opportunities and a clear understanding that his fellow villagers will otherwise spend their entire lives struggling in poverty. Setting aside personal gains and losses, he uses his foresight to find ways to increase everyone's income. He leads the villagers in experimenting with specialty crops, developing sideline businesses and trading, and establishing sales channels. Faced with numerous challenges, including skepticism and a lack of funds, he finds ways to overcome each obstacle and patiently encourages the villagers to work together. Gradually, he puts the village's resources to good use, and household incomes steadily rise. The once-backward, impoverished village is transformed, and everyone sets out together toward a better life, creating an inspiring story of shared prosperity.
