What are the characteristics of narrow-minded and vindictive people?

Physiologically speaking, people who are narrow-minded love to hold grudges and have strong revenge. They are easy to get pregnant because of a little thing, and even quarrel with others because of a little thing, which eventually leads to the point of being out of control. Next, let's look at it from the perspective of the face! If there is a deep mark in the middle of a person's eyebrows, then this person is very narrow-minded, and they can't tolerate anyone or anything. They are narrow-minded and bear grudges. Their revenge is also very strong. Once they are offended, they will try their best to get back at you. Their revenge is particularly strong, and once they hold a grudge, they will remember it for a long time.
