Can the influence of constellation on personality be changed?

The later influence is still very important. Even if two children are born at the same time, their personalities will be very different if their education methods and contact environment are different. I think the constellation is not about when others were born first, but about which constellation you prefer. There are many scales and scorpions around me, but some scorpions are like scales, one is my favorite and the other is my most annoying.

I will decide the constellation according to their personality,

It's not just a birthday.
