What about my father's extreme stubbornness? Thinking is too traditional, rigid, conservative, male chauvinistic, uneducated and arrogant.

The shortcomings of the whole traditional man are your father's. The most fundamental reason is that he has no culture and can't accept new things, so his personality is too rigid. No specific medicine can cure dad. You are a young man, highly educated and exposed to an unfathomable world. You have a broad vision and quick thinking. You need to know more about your father and learn to be grateful. It is such a father who raised me with his heart and made me more aware of the truth of being a man. Thank your father, so that you can get along with him easily. Do more communication. With the growth of age, my father's temper and temperament will gradually change.
