Constellations and people's personalities are completely opposite. What happened?

Normal, I think there is only 12 constellation here, but there are tens of billions of people. With so many personalities, how can the constellations be summarized? Moreover, as far as I know, this person's personality in the constellation is fixed and will not change for hundreds of lives. However, people's personality will change in different periods, so it is normal to go against it. Attachment: There are constellations such as the moon, the sun, Venus, Mercury, Saturn, etc. Generally speaking, it is the sun constellation, so of course, a constellation can't be complete. I don't think most people can only meet the characteristics of a constellation, just like me and my constellation in many ways.
