I personally think it’s because since ancient times, “Niang” has been the most important person in everyone’s heart, the closest person, so when you curse someone with “Niang”, you can hurt others. Our lives come from our parents, especially our mothers, who treat us as their darlings and are afraid that we will be a little wronged. Therefore, most people love her as much as our mothers love us, so they are used to it when we quarrel. Of course, these are the most intuitive ideas to scold the person the other person loves the most, but speaking from ancient times to the present, there are actually many reasons.

The first is the division of clans brought about by the patriarchal system, which makes the nobles feel superior and oppress the poor. The poor complain so much that they can only scold their ancestors behind their backs. The patriarchal system is actually used to classify kinship relationships, which is what we call clan classification. Rich people have been rich for generations because of clan relationships. Even if they have no talent or knowledge, they will not become poor, and even if they are poor, they will not become poor. Even those who are educated will remain poor for generations and suffer oppression from the nobles. Therefore, the poor do not dare to resist such unfair treatment and have no choice but to curse behind their backs.

On the other hand, women's status was very low in ancient times, and men were not only the head of the family, but also one of the representatives of a clan. Therefore, if you scolded "mother" during a quarrel, maybe Others won't argue with you, because after all, women have a low status and they won't get themselves into trouble just because they cursed "mother". But if you curse "father", you may not offend the same person, and you may offend someone. It's the whole family.

In fact, Mr. Lu Xun once mentioned this issue and wrote a special article about it, and the name of this article is "On Fucking". Although the name of this article It sounds ugly, but the analysis in it is clear and logical, and it also summarizes the curse of "mother" as a national curse. In our country, quarrels and curses of "mother" are indeed passed down for thousands of years. From ancient times, "mother", In modern times, "fuck" is a necessary word for quarrels, so Mr. Lu Xun is not exaggerating at all when he calls it a national curse.
