What if I have an extremely feudal and stubborn father?

When you are no longer paranoid that only modern science is the only correct way of thinking; When you bend down to understand the true wisdom behind the "rural truth"; When you no longer think that communicating with your father is to convince him, but just to communicate; When you are willing to think about the origin of your father's shortcomings; At that time, you will feel that your father's traditional stubbornness is only a personal characteristic, not a shortcoming that hinders communication. Best wishes.
