The extended data constellation (SIGN) refers to the "sun constellation"; That is, people on the earth are the center, and at the same time we can see which constellation is in the orbit (Greek zodiac: the circle made by animals, also known as the "zodiac"), so we can see what constellation this 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.
