As the saying goes, "Marry a strong man, and you will be rich for three to five years; marry a wise woman, and you will have three good fortunes!" Parents all hope that their children can start a family and career, choose a perfect partner, and move towards a happy and warm life after the wedding. But what conditions are considered a good family? Marrying into a good family has not only become the most concerned topic for modern women, but also a major issue that parents must face. The father of the Wu family is a senior policeman. He hopes to have a son to inherit his family, but he didn't expect that he had four daughters in a row before he had a son. From then on, the most worrying thing for Wu's father changed from finding a police successor to-how to let his four daughters marry into a good family? Dad and Mom Wu watched their children encounter setbacks and grow up in marriage, love, and family. All they could do was open their doors to them again and again, and accompany their children to learn how to love again, because no matter whether they married into a good family or not, after the birth of the baby, there will always be a door called "home" that will open for them.
