Zhou Huanfen and Wang Xiaoxia accidentally arrive in the 1970s, becoming the daughters-in-law of the Shi family. Starting from brewing and setting up roadside stalls, they persist in pure grain brewing and honest management, gradually opening up markets, supply and marketing cooperatives, and county-level sales channels. They drive fellow villagers to jointly develop collective sideline businesses, help Li Chunyan change her life through labor, and win the understanding and support of their family, ultimately running a thriving winery and making their days more and more promising.
