Constellation, zodiac, blood type, which will show your character more accurately?

According to my research and observation: first of all, exclude the zodiac, there is no objective law to find! In fact, this fate has a greater impact.

Blood type: A: introverted, affectionate and emotional; B: extroverted, emotionally divergent and emotional; O: extroversion, emotional self, emotional control; AB: Introverted, emotionally passive, and disliked emotions.

The constellation determines more, so I won't say it here.

In short, there are their own inevitable laws. For example, people with different blood types in the same constellation are very different. The range of blood type determination is very large, and the constellation determines a lot, so we should look at it together.
