It is even more wrong to combine people who are not destined for love. Niu Cheng, a handsome private teacher, comes from a poor family and has met four women successively. His wife Xiaolan is a virtuous and energetic person who is diligent and thrifty in running the family; his primary school teacher Gong Gong is youthful and beautiful but has a perverse temperament; and his twin sisters Shu Jinhua and Shu Yinhua are charming and generous. He moves through it like a fish in water, showing true feelings everywhere. The time spans nearly twenty years, the story originates from life, and the subject matter is close to ordinary people, including well-known engineering fields, family planning, flood fighting and rescue, working to buy code, etc. There are both authentic rural life and bizarre urban scenes, which fully demonstrate the emotional entanglements of contemporary people, folk customs and habits, and are simple and realistic.
