Two chemical molecules（分子）on the red blood cells make people's blood different．Scientists mark one molecule "A" and the other molecule "B".
According to which and how many molecules are on the red cell, scientists divide blood into four types: A, B, AB and O.
Your blood type will stay the same your whole life.
Scientists have been wondering if there are some links between people's blood type and their personalities but they don't know for sure yet.
But some say that people with the same blood type may have things in common.
What's your blood type? Do you have family members or friends who are the same type as you? Read the following. Are you like this?
People with type A: They look peaceful from the outside. But they ask too much of themselves that they may be very nervous inside. They get happy or sad easily. Sometimes they are shy but always very careful. They can easily win people's trust.
