In 1985, the reborn Jiang Hao returns to the day his wife gives birth to a child. In his previous life, he favored sons over daughters, sacrificing his three daughters in exchange for doting on his only son, only to be abandoned and starve to death in old age, dying full of regret. In this life, he completely reforms, treats his daughters well, and unexpectedly binds a shopping cashback system — he can get cashback whenever he shops. From then on, relying on small business and hard work, he gradually saves money and turns his life around. Facing entanglement from his wife's family, family conflicts, and the tide of the times, he protects his daughters, mends family bonds, and leads the whole family from a small earthen house toward a better life.
