A modern migrant worker accidentally passed through the fetus of the Liu family in Daqi countryside and became a five-year-old girl named Liu Cenxin. The family favors the eldest son who is a scholar, while the second son's parents are hard-working and live in poverty. Relying on the memory of her past life, she found rare dendrobium in the cracks of the hot springs in the back mountain, went to the market to set up a stall and hawked, gradually saved money, raised money for her brother's private school, and broke away from the shackles of the big family with her miserable second wife, and explored the way to wealth for a poor family in the mountains and wilderness.
