Are constellations really smart?

There must be something accurate about the constellation, otherwise so many people won't believe it. I believe that people in each constellation have their own characteristics. For example, Aries is mostly cheerful and Scorpio is mostly introverted, which has been verified by friends around me.

Because each constellation has a different personality, the relationship between constellations is related to their own personality, and whether the constellations match is also analyzed according to their personality.

Sow a character and reap a destiny. Since personality is like this, fate will also be affected, so there is a certain connection between constellation and fate.
