Are people in the same constellation similar in character?

Most of them are, but I know one with a big contrast, which may be caused by the poor family environment and living environment.

In fact, the constellation is just a statement and cannot be used as a basis; However, people's personality is called "all kinds of people" and cannot be simply planned as "constellation theory" Even if it exists, it is only a coincidence or accidental phenomenon, and it is by no means a law or a truth conclusion. Don't use this as a reason to infer people's character, mislead people's children and make people laugh.
