The Luo family, which opened a skewers shop on Good Luck Street, is a reconstituted family. The widowed father Luo brought a pair of twins, and the divorced mother Luo brought a daughter. The two got together and had a little daughter after marriage, becoming a rare family of six. The Luo family lives a plain and warm life, and the neighbors envy them as a "lucky family". The old couple hopes that their children's "small families" will be as happy as this big family, but they don't know that their children have their own family crises or life pains, but the filial children are worried that their elderly parents can't bear it, so they choose to hide it temporarily. In the end, with the help of Luo's father and mother, the children all found their own happiness. The second daughter, who is a doctor, and her son-in-law separated because of personality problems, and finally got back together after going through the test. The well-behaved little daughter plucked up the courage to go back to college, and finally became a couple with the second son-in-law's younger brother.
