In 1982, eight-year-old Gu Siqing wakes up, returning to the era when the Gu family was looked down upon for having only four daughters. Armed with memories of her past life, she is not in a rush to defy the heavens and change her fate, but simply reminds her parents to seize the opportunities of reform and opening up, go south to source goods, open a clothing store, do wholesale, run a Guangming supermarket, and then turn their money into Beijing courtyard houses. Each of the four Gu sisters walks out into a brilliant life: the eldest sister is steady and capable, the second sister is shrewd and resolute, the third sister steps onto the competition arena through diving, and the youngest grows from a prodigy student into a well-known writer. Outwardly, there is preference for boys over girls and scheming relatives; inwardly, there is family support and Han Zhengping's watchful waiting. Relying on courage, vision, and unity, the Gu family turns a life looked down upon into an enviable existence.
