Why do people in the same constellation have great differences in personality?

There are no two identical leaves in the world, and there are no two people with identical personalities in the same world. Nowadays, people always like to judge a person's personality by constellations, but people find that even people with the same constellation have great differences in personality. What is the reason?

The knowledge of constellations is particularly complicated. They are not only divided into sun constellations, but also into moon constellations and rising constellations. In the systematic knowledge of constellations, these three constellations constitute a complete astrolabe. The twelve constellations often mentioned refer to the Sun Constellation, and the Moon Constellation and Ascending Constellation also affect personality and behavior.

In my opinion, it is particularly one-sided to say that constellations will affect a person's personality. The formation of a person's personality is related to family environment, education level and life experience. It is especially one-sided to judge a person's character only by constellations.

Although the constellation is imported from abroad, in my opinion, it is almost the same as those feudal superstitions in ancient times, and it is ok to use it for entertainment, but if you are too convinced, it will only add trouble to your life.

Even, many people look for jobs, make friends and find lovers according to the horoscope. In my opinion, this kind of behavior is simply stupid, and there are thousands of people. How to judge according to the constellation?
