In a rural village during the 1970s and 1980s, the Meng family's second branch faces constant criticism for having only three daughters and suffers from the elders' favoritism during the family property division. When their father falls seriously ill, the enormous medical expenses push the family to the brink. The eldest daughter, Meng Niandi, gives up her place at a prestigious high school and learns to make tofu to support the family. The three sisters stand by one another, while their mother, Luo Suqin, tenaciously holds the household together. Despite difficulties caused by relatives, malicious rumors, and deliberate schemes, they remain committed to honest business practices, transforming a small tofu workshop in the stable into a large factory with collective investment. Each sister pursues her own dreams through medical studies, education, and industrial entrepreneurship. Through hard work, they shatter outdated beliefs and prove that women can build their own homes and earn their own glory with their own hands, without relying on their gender.
