Synopsis: Reborn back to the day when my younger brother stole the family's food stamps for candy for the first time. Instead of reporting him, she took her brother to collect scrap metal and dig herbs, using legal labor in exchange for a meager income. Her younger brother had a talent for mathematics, so she saved his tuition to buy old textbooks and encouraged him: "Knowledge cannot be stolen." During the turmoil, her younger brother's mathematics talent was used to settle "political accounts," but she tried her best to stop it and let him pretend to be sick to avoid it. In 1977, his younger brother entered college and became a mathematician. In his later years, his brother said: "Sister, you pulled my life back from the edge of the cliff inch by inch." She said: "You walked back by yourself, I just didn't let go."
