From the Start, in a Year of Famine: The Self-Sacrificing Sister Wakes Up

A time-travel story set in the 1960s, with a pocket dimension, famine, hoarding supplies, making money, and raising children. Chen Chunxia, a multinational company's CEO, transmigrates to 1960, during a famine, into the body of a woman with the same name. The original is a shameless enabler of her younger brother, unloved by her husband's family but cherished by her birth family. Her scumbag soldier husband despises her, but at least she has two children who love her. She transmigrates with her pocket dimension and refuses to keep enabling her brother. She tears into her parasitic younger brother, wicked mother, cruel mother-in-law, and scumbag husband. While everyone else goes hungry during the famine, she has all the food and meat she could want and lives more freely than anyone. With supplies so scarce, a secure job is the prize of the age: whoever can get hold of supplies can take their pick of jobs. During the famine, she helps her neighbors make it through. After her soldier husband betrays her, how does a country woman put the scumbag in his place? With the original owner's children by her side, she rises to the top.
