Transmigration: A Flower of the Struggle in the 1970s

Ma Lianhua transmigrates to a rural village in another world's 1970s. Unused to physical labor and clueless about farming, she's left wanting to cry, and nearly drops out of school to get married. She thinks the System she's activated will be a transmigration cheat, her golden finger, but it turns out to be an expert at digging pits and a master of setting her up. After witnessing the tragic fate of the Ma family, Ma Lianhua can't stand by and do nothing. She can only make herself stronger and change the fate of her whole family. But why does this life keep feeling more and more familiar? Is this really transmigration, or a prank by the researchers...?
