The third child has leukemia, and Jingqiu saw the third child when he was dying. He was skinny. Jingqiu knelt down in front of the bed, took the third child's hand and said over and over again, "I am Jingqiu, I am Jingqiu ..." She shouted and stroked his eyes. His eyes finally closed, and two tears rolled down from the corner of his eye ... The third child left, and according to his last wish, his body was cremated and buried under the hawthorn tree. Old three gave his diary, letters and photos to Jingqiu to his younger brother before his death, and told him not to give them to her if Jingqiu was happy. If her love is not smooth, or her marriage is not happy, give these things to her and let her know that there was once a person in this world who loved her with all his heart and soul. The title page of the third diary reads: "I can't wait for you for a year and a month, and I can't wait for you to be twenty-five, but I will wait for you all my life."
