Traveling through the Northern Song Dynasty, the family was surrounded by walls. Zhao Shoutian, a researcher at the Academy of Agricultural Sciences, started from two acres of sandy land with a head full of modern agricultural knowledge. He planted peanuts, pressed oil, opened a farm cooperative, set up factories, and ventured overseas to create a "peanut oil empire" across East Asia. At the same time, he trained his son to become a scholar and become a scholar in high school. This is a hard-core farming novel that integrates agricultural planting, commercial management, family education, and officialdom. It looks at how technology flows use hoes and abacus to leverage the entire era.
