Last night, when a beautiful female boss invited me to drink, he asked me such a question: They all said that the ugliness of the family should not be publicized! So, please tell me, why?

I suddenly fell into confusion, although I have known the sentence that family ugliness cannot be publicized for decades, but I do not know the connotation of this sentence, and I do not know why?
I quietly sent this why to my friend, and the friend replied: A person can't even handle the affairs of his own family, and he also publicizes the ugly things in his family, what face is there in front of the world, and how can he deal with the relationship with others?
The friend's reply seems to have some truth.
Yes, between families and relatives whose fire is hotter than gray, there will definitely be some conflicts more or less, after all, sometimes, their teeth will bite their tongues...
However, after all, it is the affection of blood thicker than water, that is, the blood relationship that breaks the bones and tendons, which is what we call the old saying: the fierce wind cannot blow for a hundred days, and the anger of relatives cannot be a hundred days.
After all, in the rolling red dust of the world, there are a hundred different kinds of people...
Therefore, there will always be some people who will vigorously declare the so-called family scandals between mother-in-law and daughter-in-law, femininity contradictions, brotherly disagreements, etc., and become an authentic non-human.
We all know that those who are right and wrong must be non-human...
If you think about it, is it very scary that people who come to us and keep talking about their ugly family are very scary?
Speaking of parents who gave birth to themselves, brothers and sisters of a mother-in-law, or concubines who rebuked the destiny of the world, are these all internal contradictions of the family with teeth bitten to the tongue, that is, the so-called family ugliness?
"Family ugliness is an internal matter of family members, and when it is spread out, there can only be a hundred harms, not a benefit!" Have you forgotten the truth of family discord and being deceived? Therefore, the ugliness of the family should not be publicized, which has been the norm of our life for thousands of years. "I took the question raised by my friend and called a master of traditional Chinese studies, and he said this to me.
Writing this, I suddenly remembered that the math teacher in junior high school once said to me: In fact, people are more and more confused the more they learn.
Looking back now, the teacher's words are really the truth, just like many of us, it can be said that after ten years of reading books, walking thousands of miles, and reading countless people...
However, after knowing a lot of truths, I found that I didn't know what was the real truth!
Just like this saying that has been passed down through the ages, "the ugliness of the family must not be publicized", I don't know why?
Dear friends, please tell me, why is the ugliness of the family not to be publicized?
