My father is 60 years old, and his family conditions are average, but he is particularly proud. He is always out to save face, either bragging or quarreling with others. Why doesn't he understand?

Because your father loves face more. Therefore, others are not allowed to say unpleasant things in front of him. Once you hear something you don't like, you must argue with others. It is inevitable to quarrel with others. It may also be because I love face, so I have a strong self-esteem. So in order to maintain their self-esteem. In order to save face, you may brag. It may still be influenced by some old ideas. As the old saying goes, people live with a face and trees live with a skin. Although the old man is 60 years old, he is more vain. Be competitive. It may be better to communicate with the elderly slowly.
