Vanity is a psychological state of human beings. Regardless of ancient and modern China and foreign countries, men and women, old and young, rich and poor, have self-esteem. If self-esteem is distorted, it is vanity. It is an excessive expression of self-esteem, a personality defect that pursues emptiness in appearance, and a social mood and psychological state that people show in order to gain honor and attract universal attention.
Vanity is manifested in behavior, such as blindly comparing with others, ambitious, too concerned about other people's evaluation, too eager for self-expression, and easily jealous.
Vanity seems to have a strong sense of honor, but it is actually a response to moral honor.
In fact, we often see such a scene in our life:
Buying a house is not for living, but for showing others. When choosing a house, don't do what you can, just apply it, blindly pursue big and decent, and have insufficient economic strength. You also need to borrow a large sum of money to buy a big house envied by others and become a house slave.
Buying a car is not for contemporary tools, but for showing off and earning face.
