What is the basis of the constellation?

Constellation 12 is a calculation method based on the zodiac. This method has continued to this day and is still accurate, but the sky has changed. The zodiac is now 13 star, but the fate of 12 star is still correct. In other words, if you study astronomy, it can be said that it is 13 stars, but if you want to tell fortune, it is only 13 stars.

Constellations are about western constellations. Western astrology mainly calculates the "personal astrolabe" as an explanatory basis according to the astrology at birth, such as the position of the sun, the moon and the five stars in the zodiac. We generally say: Aries, Taurus, Gemini, Cancer, Lion, Virgo, Libra, Scorpio, Sagittarius, Capricorn, Aquarius and Pisces are all classifications of western astrology!

Chinese astrology is based on twenty-eight nights (see twenty-eight nights in Sanyuanli) or twelve o'clock and the dividing line, observing the sky and its area, so as to predict the events that will happen in the state and country on the ground corresponding to this area; Predicting the fate of emperors and their families, China's astrology is called Wei Zi's number-playing.
