Is the constellation real or not? Is it useful?

Constellation analysis came from the west, but the real constellation analysis is very complicated, and all the celestial phenomena should be considered at birth. But now we generally say that the constellation analysis is mostly about the sun constellation, so it seems that people are simply rated as 12.

I think constellation analysis is reasonable. I dare not say scientifically, but it is also possible that the attraction of celestial bodies may have a certain impact on people's personality. But I think astrology is not accurate.

Now all the tests done online are simplified, so you can't believe what it says. Let's make a reference.
