Clinical blood use is in a state of "tight balance" for a long time, and patients often fall into a life-threatening crisis due to ischemia. Some seek help from the "blood head", while others organize mutual assistance. The intervention of public welfare forces has promoted the awakening of blood donation awareness. Many people who have experienced the pain of ischemia have turned to become long-term blood donors, and bags of hot blood have gathered the warm power of mutual assistance.
