The origin of the constellation:

In ancient times, in order to identify the direction and facilitate the observation of the sky, the stars scattered in the sky were connected by imagination, and half of them were named in ancient times, and their naming methods were attached according to the myths and shapes of ancient civilizations. The other half was named only in modern times, often named after navigation instruments.

In ancient times, the way of "Lianliankan" was different because of different regions. 2 1 century, the world unified the constellation map and divided the sky into 88 regions and 88 constellations. The constellation we usually say refers to the sun constellation.

That is to say, people on the earth are the center, and at the same time, we can see which constellation the sun is in orbit (Greek zodiac: meaning ~ circle made by animals, also known as "zodiac"), so we can say what constellation that person is. In fact, the origin of this constellation is different from that of the West and the East, and the arrangement of the lunar calendar is also different.

More than 2000 years ago, the Greek astronomer Hipparchus (190 ~ 120 BC) divided the ecliptic into twelve segments, with spring divided into zero, and every 30 degrees from the vernal equinox (that is, the zero degree of the ecliptic) as a palace, taking the main constellations contained in each palace at that time.

In turn, Aries, Taurus, Gemini, Cancer, Leo, Virgo, Libra, Scorpio, Sagittarius, Capricorn, Aquarius, Pisces and other houses are called the zodiac. There are twelve constellations in all. Babies born when the earth moves to every fraction (constellation) will always have some similar characteristics when they grow up, including behavioral characteristics.
