There is a blood donation vehicle parked on the square opposite the government, and the banner in front of the vehicle clearly reads: Type O blood is urgent! I have blood type O, isn’t that right! For nothing else, just seek psychological satisfaction. Then stepped into the car in two steps: “I want to donate blood!”
  “Is it type O?” the person in charge of the blood draw asked.
  “Yes”
  “Is there any illness?”
  “none”
  “Fill in the form!” I saw an empty form to be filled before blood donation and was thrown in front of me. After filling out the form, I quickly rolled up my sleeves and waited for the sacred moment.
  “How much weight? Why don’t you fill it in?”
  “96”
  “What, do you have 96 kilograms?”
  “Heh, what look in your eyes! I’m 96 pounds”
  “Go, go, go, what’s the mess?”
  “What’s wrong? Isn’t it O type blood in a hurry?”
  “It is an emergency of type O blood, but you can’t draw everyone’s blood!”
  “Why?”
  “Why? People who weigh less than 50 kilograms can’t donate blood, otherwise they will feel dizzy, and O blood will be in a hurry.”
  I stuck out my tongue and got out of the car in a desperate manner.
