Why is there a 12 constellation?

The zodiac should be completely the zodiac. The ecliptic is all * * * 360 degrees, divided into twelve regions, and each region happens to have a constellation, so it is named after this constellation. In fact, the principle of astrology is to consider the position of the planet on the ecliptic, and the constellation is only used as a marker. For example, this sign is in January and February. Similarly, there is no need to use terms such as Aries and Taurus, which are called the first constellation and the second constellation, and it does not affect the astrological results. Therefore, whether there are 12 constellations or 13 constellations on the ecliptic has nothing to do with astrology.

As for the principle of astrology, this is not clear for the time being. . Simply put, it is the function of some invisible force. Heaven and man are connected.
