Where is the bigger blood donation station in Mianyang?

Don't be bloody . . . . . . I strongly object. My teacher is a WD tutor. We are all medical students. On the surface, blood is glorious. In fact, the blood bank divides the blood of blood donors into blood components, that is, red blood cells, white blood cells, platelets and plasma, and then sells more than 3,000 bags. Violent group, the hospital teacher told us never to draw blood, which is just like an outsider, not a medical student, not a hidden rule of the medical profession, but you must go.
