Ninety-year-old Wang Xia accidentally is reborn, returning to 1980 when her eldest son just passed away. Thinking of how her family members successively dispersed and died out in her previous life and how she died lonely in old age, she resolves to rewrite the destiny of the entire family. Unexpectedly, the trash can that time-traveled together with her can actually recycle waste and exchange it for supplies! She has her widowed daughter-in-law go work at the factory, raises and educates her children and grandchildren, reconciles family matters, and relies on haircutting, setting up a stall, and running a small grocery store to live a life that becomes more and more prosperous. From a shrewd family head to a daring and ambitious business person, Wang Xia grabs money with one hand and protects her family with the other. In this lifetime, no one is allowed to fall behind!
