Star is an astronomical term, which refers to the place where the sun, moon and five stars live. A night usually contains one or more stars. The ancients divided the vicinity of the ecliptic into twenty-eight groups, commonly known as "twenty-eight lodges". Because the rings of twenty-eight hostels are arranged in four directions of the sun, the moon and the five stars, which are very similar to the places where the sun, the moon and the five stars live, they are called "hostels".
Twenty-eight stars, also known as the Twenty-eight Palace or Twenty-eight Stars, divide the stars in the southern transit into twenty-eight groups, and the circle of stars distributed along the ecliptic or the celestial equator (the equator of the earth extends to the sky) is divided into four groups, also known as four elephants, four beasts, four-dimensional and four-dimensional gods, and each group has seven stars. Its origin is still not completely clear.
Mention the role of stars
Twenty-eight stars are an important theoretical basis for the ancients to infer the good or bad luck of a day. Twenty-eight stars are widely used in metaphysics, such as geography, choosing the date, Yi-ology and divination. There are seven hostels in the southeast, northwest and northwest, with different star ratings. East Seven Hotel has 32 stars, South Seven Hotel has 64 stars, West Seven Hotel has 5 1 star, and North Seven Hotel has 35 stars, all of which are 182 stars, following a certain track. We call it the ecliptic.
The "auspicious day of the zodiac" is calculated according to the stars as a reference.
