Why was Ophiuchus expelled from 12 constellation?

In western countries, people are often very disgusted with the number 13, and all the numbers about 13 are cleverly avoided by them.

There is a reason why they hate 13 so much, because westerners believe in Christianity, and the founder of Christianity, Jesus, was betrayed by his thirteenth disciple and then killed, so westerners think that the number 13 is unlucky.

Moreover, in western countries, people still think that on the day of 13 every month, 12 witches will hold a carnival, and 13 demons will also appear at the climax of the party, which will bring disaster to people. So the number 13 is taboo in western countries, so they only keep the twelve constellations.

2. Not everyone loves the legend of Ophiuchus.

Ophiuchus symbolizes the god of medicine. Asclepius caught a giant snake with both hands. After his mother Colonis was killed by the golden bird, he tried to save her with a giant snake. Therefore, Asclepius got the title of Ophiuchus. However, Pluto, the god of hell, knew that he had violated the dogma, so he killed Asclepius with lightning.

3. Astrology has only twelve paragraphs.

From the astrological point of view, the division of the zodiac in astronomy is meaningless to astrology. Now the zodiac mentioned in astrology is actually just a symbol, which does not correspond to the real constellation with the same name. Astrology is a system to explain or predict people's fate and behavior through the relative position and movement of celestial bodies. Because only twelve sections overlap, only twelve constellations are selected, and Ophiuchus, the thirteenth constellation, has no chance to enter the twelve constellations.
