1. In front of the other person, don't have a good impression of other people of the opposite sex. Type O people hate the kind of exquisite people in front of them.

2. Don't let people be speechless, especially for men. Don't object to the opinions insisted by the other party on the spot. But to put a paragraph, I will talk about it in a few days.

3. The above attitude towards giving orders is particularly easy to annoy the other party.

4. Don't make the other party listen to you all by yourself.

5. For people of other blood types, you should naturally pay attention not to touch the other person's inferior place, especially O type, and absolutely not to do so.

6. If there are important things between two people, they should talk to each other in person. If someone is caught in the middle for indirect conversations or relayed by others, it will provoke the other person to anger.

7. If you want to give a tooth for a tooth to someone who loves tricks, you would be wrong. ( Blood type and personality http:///xx/)

8. Blaming the other party's character, such as saying that he (she) is simple, innocent, likes to look at the immediate interests, centered on me, etc., the other party will get angry. When the other person realizes that you have this opinion of him (her), they will be even more angry. If you say that others are good in front of the O type, the male O type may not necessarily believe it, but if you say that the O type is a poet, many people will feel very happy. Generally speaking, it is better not to comment on the O-type character.
