In the summer of 1966, a great disaster befell a happy family in Shijia Village, Laizhou. The fourth child of the Shi family had his cervical vertebra broken by the rubble from the blasting of the mountain in the quarry. The three elder brothers took the fourth brother and overcame numerous difficulties and dangers to go to the county town, Yantai, and Beijing, but in return, they received a diagnosis that the fourth brother was paralyzed from the waist down and could only survive for half a year. In order not to let the fourth child despair, the brothers made up a "beautiful lie" to restore the fourth child's confidence in fighting the disease. The whole family overcame hunger, poverty, and fatigue, and took care of the fourth child tirelessly. But an unexpected letter let the fourth child know the truth. For the hope and confidence of his family, the fourth child decided to pretend not to know and receive treatment. But the miscarriage of his eldest sister-in-law and the death of his mother made him want to live again. The eldest brother finally woke up the fourth child: There is no secret recipe to cure the disease, just hold on! For the sake of his mother and eldest sister-in-law, he must hold on. The fourth child regained confidence, and at this time he had spent half a year, he did not die, and was still alive and well... In the 1980s, the fourth child fell in love with the music teacher from the city. The brothers and sisters-in-law discussed the question of "should the fourth child love?" Despite different opinions, the whole family overcame various difficulties to create a "perfect day" for the fourth child and the music teacher. The fourth child had no regrets. He bravely expressed his feelings like a healthy person and experienced the taste of love. Entering the new century. The healthy fourth child thought about the "meaning of existence and the value of life" in his heart. The brothers decided to let the fourth child take charge of the family to untie his knot. At this time, the second child suffered from uremia and urgently needed a kidney transplant. As the head of the family, the fourth child resolutely decided to donate a kidney to the second brother. Brothers are in trouble, they must face it together. But in the end, the second brother's condition worsened again and he was on the verge of death. In order to meet the second brother's dying wish, the fourth child stood up with the help of the whole family. He created a miracle. This is the meaning of the fourth child's life and the meaning of life for the whole family. For forty-five years, and more than sixteen thousand days and nights, under the careful care of the whole family, the fourth child had no other illness except high paraplegia until the day he left this world. Because of this family, the fourth child lived such a life - healthy, fulfilling, happy, and with love.
