Why Ophiuchus appeared, Ophiuchus's character and constellation.

The southern part of Ophiuchus belongs to the starry sky of Scorpio (northeast of Scorpio) in the ancient constellation distribution. However, in the later astronomical division, the bright star of Scorpio was too south and the northeast was dim. And Ophiuchus has nowhere to put its feet, so I gave this starry sky with ecliptic to Ophiuchus.

So Ophiuchus does not belong to the zodiac, but it does cross the zodiac. From the constellation, Ophiuchus should be similar to Scorpio. ?
