Is the constellation true or false? I remember seeing who did an experiment in a composition.

Fake. At first, constellations were used by the ancients to time and distinguish seasons and directions. People who discuss constellations only summarize the most obvious characteristics of some people, and then find that many of these people with similar personalities have similar birthdays. For example, although I am an Aquarius, I have no stars, whether it is ascension, zenith, moon, mercury, Venus, etc. I am in Virgo, but I feel that I have strong picky and Virgo's neat personality.

Learning to observe people and often summing up their personality characteristics is the most reliable way. It can be said that constellations affect personality and have low reference value.
