The Zheng family in Longcheng is a very common big family, the older generation has a close relationship, and the three cousins and brothers of the younger generation are also like relatives. Cousin Zheng Dongni (played by Ma Yili)'s parents, uncles and aunts, have been in a discordant relationship all year round, and they are constantly beaten and scolded. Her broken upbringing fostered her rebellious and flamboyant character. She longed to get rid of the influence of her original family, so she married abroad. Zheng Xiju (played by Bai Yu) has a gentle personality and is tolerant and generous. His parents died when he was a child, and he was raised by his three uncles and aunts, so he stayed in the big family in Longcheng to repay his kindness. The younger sister Zheng Nanyin (played by Li Tingting) is the child of three uncles and three aunts, compared to Dongni and Xidu, she has a perfect family, the protection of her brothers and sisters, and is innocent and romantic. Xidu helped the uncle who suffered injustice to change his life, but he suffered an unforgettable lovelorn, but fortunately, Dongni's best friend Jiang Yi appeared at the right time, and the two gradually established a relationship. Zheng Dongni's marriage with her doctor's husband Fang Jinghui evolved into chicken feathers and duck blood, and a divorce and child war was fought from abroad to Longcheng. Zheng Nanyin got a marriage certificate just after going to college in order to resist her mother's control, but she didn't expect that the campus husband and wife would mourn everything and go back to the big family to recuperate. The three sisters and brothers have different fates due to different choices, but they always influence each other and warm each other. Whenever they are in trouble, the big family can always give the three siblings the deepest support. And as they grow up, they are also feeding the Zheng family in their own ways. In the end, Dongni grew from a rebellious girl to a mother who shouldered the responsibility of the family, and Xidu, who has always been thinking about others, has her own life. Nanyin has also found herself and become an adult who can take charge of herself.
