More than 2000 years ago, the Greek astronomer Hipparchus (190 ~ 120 BC) divided the ecliptic into twelve segments to mark the position of the sun on the ecliptic.

The spring is divided into 0, and every 30 degrees away from the vernal equinox (that is, zero degree of the ecliptic) is a palace, and it is named after the main constellations contained in each palace at that time, which are Aries, Taurus, Gemini, Cancer, Lion, Virgo, Libra, Scorpio, Sagittarius, Capricorn, Aquarius and Pisces in turn, which are called the zodiac.
