I immediately recognized Principal C, a middle-aged man in his early forties, standing in front of his desk. Air Force General Hospital Hematology Research Center Xue Mei He has not changed much and looks more radiant than before, since his son was discharged from the blood ward, probably haven’t seen him for several years. The young man beside him I couldn’t recognize at all. The original was Little C. I really couldn’t recognize him at all, he’s grown a lot taller, a full head more. Come to the hospital for a review? I said. No, I sent my son to college, said Principal C, glancing proudly at his son beside him. Which university in Beijing did you get into? I asked, also very happy. I knew that Little C had always studied very well, even though he had received a bone marrow transplant from leukemia a few years ago, when he had just started his first year. Not in Beijing, the school is in Tianjin, because passing through Beijing, so make a special trip to visit all the doctors in the hospital. Today is Saturday, it seems that you only see me one, I looked at them both. As we were talking, Dr. Yan, who took my shift, came in through the door, and when she knew all this, she too had a happy face. Especially when the patients they treated, a few years later still remembered themselves and made a special trip to the hospital to visit everyone, really touched. As we talked, we unknowingly pulled back to the scene 6 years ago. For this pair of father and son, it is indeed an unforgettable memory. The principal said, nothing else, chemotherapy, radiotherapy, decontamination ward 。。。。 The principal said, “At that time, we were under a lot of psychological pressure, because our son had no other choice but to have a transplant. We, as a couple, really wanted to save our child, and we had to work hard even if there was a little hope. Principal C said a lot in one breath, very excited, I saw his eyes were moist, his eyes were red. Then, he bowed his head, and that bowed head may only want to omit the infinite sadness and joy. Know F, he is now well. Dr. Yan said to the principal, turning the conversation in another direction. Know, know. Principal C’s expression was sunny. Before saying goodbye, Principal C took out a plastic bag of tea from his hometown from his black bag and left it for the doctors and nurses in the department to taste. We saw the father and son leave the ward, we felt a pang of emotion, I hope every leukemia patients are like little C such a good thing.
