Wang Xiaoyi, a woman fleeing famine, refuses to be enslaved by a wealthy merchant and joins forces with Zhao Tiezheng, a blacksmith, to claim barren saline-alkali land. With her extensive agricultural knowledge, she invents the curved-beam plow, builds greenhouses and heated kang beds, and improves farming methods. She leads the villagers in fighting droughts and pests while providing relief to refugees through work. Together, the two bring prosperity to the region and receive official recognition. When an imperial inspector misunderstands their efforts, they prove themselves through hard work and the support of the people. Remaining true to their commitment to farming, they use technology and compassion to build a home where everyone can live and work in peace.
