What should I do if my wife quarrels with my father?

If you teach your son in front of your wife and behind your back, you need to educate your wife. If she can't change... There is only one father, the one who trains you and educates you. You must respect your father at any time.

If there is no choice but to choose the father, why should a man be without a wife?

It is difficult for a wife like you to raise an excellent descendant for you.
