The place where Qingshan in Wuhan comes to the door for injections and infusions is the clinic. The clinic can provide on-site injection service, provided that the elderly and young people who are inconvenient to walk around at home for a long time still have to take a taxi to the clinic themselves. Eat properly before the infusion bottle, do not eat on an empty stomach or for too long, and drink liquid food to avoid transfusion reaction.
