Why can't a man and a woman get married if they are 6 years apart? Elders say that a 6-year age difference is a conflict. Is this true?

It’s all nonsense, it’s all feudal thinking. In fact, it doesn’t matter if you are 6 years old. It doesn’t matter if you are 16 or 26. My parents and my mother are only 6 years apart. I have never seen them become famous when I grow up. No matter what the face, you can’t believe all the feudal thoughts, but some of them still make sense. Some adults also say it to scare children. For example, the lunar eclipse means that the tengu eats the moon, right? It’s very retarded to ask this question now, but I didn’t understand it before. You just said that, so the 6-year age difference is not a problem at all! It’s not believable
