When patients with hematological diseases urgently need blood to prolong their lives, and patients with excessive blood loss (such as bleeding women or surgical patients) urgently need blood to ensure their lives, donating a bag of blood can give them a chance, but donating a bag of blood will not bring harm to blood donors.

Therefore, blood donation without compensation is a pure altruistic behavior and a civilization. There is no benefit to the country and the people, and there is no egoism. The so-called benefit for one family is the slogan of fooling people promoted by domestic practitioners.

I have been donating blood for more than ten years, and I have never felt any benefit to the country, my personal interests and my family. I always listen to some bad places to donate blood for free, but this is useless. My city has never been so deceptive, but blood donation without compensation is the best in the country.
