What does it mean that children are not lonely when they are tortured by flesh and blood?

The words "when a teenager is in trouble, his flesh and blood will be punished" seem to come from the mouth of a gossip or four-pillar prediction wizard, which is similar to the fortune teller and his description of the fortune teller's prediction results. The phrase "young people are troubled" is easy to understand, that is to say, so-and-so has more frustrations and hardships in his youth, and he belongs to the kind of person who has a bitter life in his youth. In fact, there is nothing difficult to understand in the sentence of "the flesh and blood punish each other" in modern Chinese. "The flesh and blood" generally refers to the immediate family members who are related by blood, while in the folk, it refers to the "six relatives" in the "six relatives disown", that is, parents, brothers and children. In fact, here, "flesh and blood" should have its specific meaning, that is, it generally does not include parents and other relatives, but refers to children raised by themselves, and sometimes includes brothers and sisters. "Punishment" means punishment and prison litigation, and in today's words, it means "litigating" and "being a defendant"; In ancient times, it may refer to more serious lawsuits, namely imprisonment and exile, as well as corporal punishment and even execution. "There is a penalty", that is, there is the possibility that these unlucky things will be spread. Of course, the above is just a simple analysis of these two sentences in a direct sense. It should be said that the basic meaning will not be too different. However, if the above two sentences are really from the mouth of a fortuneteller, I think we should re-understand them from two aspects: First, how scientific and credible are they? To put it bluntly, it is necessary to seriously doubt whether these two sentences are accurate. There are many tricks in this regard! Second, objectively speaking, life, from small to large, has to go through some ups and downs, and anyone will inevitably encounter some troubles and setbacks; Especially in modern society, everyone faces an extremely complicated society. With more and more frequent interpersonal communication and closer interpersonal relationship, there will inevitably be some collisions and entanglements between people. It is really normal for a wife to have some lawsuits and stand up and have some lawsuits. If you don't grasp it well, of course you have to bear greater legal responsibility. In fact, we should have a correct understanding of these things and learn to deal with them with a positive and correct attitude. I think, if we know this, it will be much more meaningful than just knowing and remembering the sentence "when a teenager is in trouble, his flesh and blood will be punished", don't you think?
