Modern woman Jiang Yingqiu accidentally time-travels back to 1974, falling into the water and becoming a widowed educated-youth, raising three young children alone. She accidentally acquires a bronze cornucopia capable of replicating physical items, relying on this fortune to solve her family's food and clothing needs. As a minban primary school teacher, she tries every possible means to improve rural schooling conditions, leading the production brigade to use ponds for fish farming to increase income, overcoming obstacles such as neighborly gossip and policy risks, building schoolhouses, earning collective funds, and on the barren soil, protecting her children, leading the fellow villagers, and starting a new life of self-reliant struggle.
