Cheng Wanwan wakes up in ancient Dahe Village as a 33-year-old farm wife. Four sons kneel at her bedside calling her Mom, and a daughter-in-law is about to give birth. A woman who has never had so much as a boyfriend is a grandmother by morning. Between raising four boys and surviving locusts, drought, and snow, she has one lucky break: a trading mall system that supplies what the family can't grow, and she means to get them all through the famine.
