"On May. 2nd, I received a call from the provincial Marrow Donor Program, informing me that the blood of a 15-year-old boy and mine have been successfully matched. From Sept. 9th to 11th, I had eight injections. My arms felt like they were turning into a hornet's nest. But I'm pretty used to it and feel a little uncomfortable if there's no injection waiting for me."

 

Those are some of the contents in the diary written by the brave donor, Xu Aifei, a girl from east China's Zhejiang Province. Xu said she was really surprised when she first received the phone call, because of the tiny probability of a perfect match.

 

XU AIFEI STEM CELL DONOR The Red Cross Society told me there's a boy who's suffering from leukemia, and his blood and mine had successfully matched. I was really surprised at the moment because I know the chance is only one in tens of thousands to one in several hundreds of thousands.

 

There are tens of thousands new leukemia patients every year in China. Being able to find the exactly right one is not easy.

 

XU AIFEI STEM CELL DONOR Compared to the number of leukemia patients in the country, the number of donors with the right types of blood is too small. It's too hard for them to find the right one. I feel I have the responsibility to make his life go on.

 

Learning the news was just the beginning. Injections to collect stem cells became routine work. But in Xu's diary, she just describes it as a strange, magical feeling.

 

XU AIFEI STEM CELL DONOR I have in my arms two needles, one with the blood going out and one with the blood going in. I don't know why I can't raise my arms, even though I can feel them. Many can't understand why I suffer so much just for a stranger. But I want to say that they will never ever understand the feeling when I get out of the bed. It makes me feel extraordinarily proud and satisfied.

 

After the successful collection, Xu also wrote a letter to the lucky little boy. At the bottom of the letter, it says, One day, if you recover, I'd like to meet you and invite you to my city. And then hear you say my name aloud. Gary Anglebrandt, CGTN.
