Hello everyone, I'm Qi Miao, a reporter from China News Agency. Voluntary blood donation is the general direction of the development of my country's blood business. Everyone knows that every first aid is inseparable from blood, but it is also easily ignored by everyone after the first aid is successful. "Heroes Behind the Scenes".

After a bag of blood is donated, what process does it have to go through to be considered qualified and input to those who need it?

Let's go to Qinghai Provincial Blood Center with Xiaoxin to find out!
