Fang's youngest daughter Fang Hong has just graduated from university and entered the society. Her elder sister Fang Hong believes that "the elder sister is like a mother". Regardless of Fang Hong's feelings, she is enthusiastically involved in her younger sister's work and life. The two sisters with different personalities and different concepts are constantly in friction and collision, making this originally harmonious and close family in the smoke of sisters' quarrels and fights all day long. Father Fang Ming is caught in the middle. He has lived for his daughter for most of his life, but as his daughter becomes mature and independent, Fang Ming feels that he is less and less needed. So Fang Ming began to try to find a sense of existence in his daughter's mind. In this way, the Fang family grew up in this fierce and joyful "confrontation". In the end, the younger sister found her own direction in life; the middle-aged elder sister resolved the career crisis, learned to face marriage problems calmly, and found the best parent-child relationship; the old father also found a new pursuit in life.
