Period Novel, Reincarnated in the Womb: The Female Lead and Her Brother Were Both Reborn This Way, Have Golden Fingers, and Enjoy a Warm Family Life

Looking for books similar to Famine in the Seventies: My Storage Space Is a Grain Shop (The Whole Family's Darling in the Fifties). The female lead and her brother have golden fingers, but not overly powerful ones. The whole family is warm and loving. The early parts about their life in the countryside are fun, and later she accompanies her father when he joins the army.
