Why are the names given by the ancients so temperamental?

In my opinion, the reason why ancient people named their children is because their wisdom is actually very high, and their wisdom has a poetic flavor, so the names they gave people are often very temperamental, which I think modern people can't learn. Everyone likes to play poetry books, read many poetry books, and naturally there are poetry books to flatter themselves. Names have always been considered more important. It is not only a code name, but also given by parents to their children, so they pay more attention to it, so most of them are very temperament.
