The origin of the twenty-eight constellations in ancient China is that "the corner in the room is high, the wall of the dangerous house is dangerous for bullfighting women, the belly of the pagoda is full of ginseng, and the ghost Liu Xing is Zhang Yi";

In ancient times, in order to observe the movements of the sun, the moon and the five planets (gold, wood, water, fire and earth), people chose 28 constellations near the ecliptic and the equator as symbols, collectively called 28 constellations or 28 stars. Seven stars, namely horn, sound, correlation, room, heart, tail and dustpan, form the image of a dragon.

The vernal equinox season is in the eastern sky, so it is called the Oriental Dragon Seven Nights; Fighting, ox, female, empty, dangerous, house and wall, these seven stars form a group of tortoise and snake, which are intertwined with the image of twenty-eight nights on the lacquer box of Houyi tomb. The vernal equinox season is in the northern sky, so it is called the northern Xuanwu seven nights;

Kui, Lou, Wei, Chang, Bi, Gou and Shen, these seven stars form the image of a tiger. The spring equinox season is in the western sky, so it is called the seven nights of the western white tiger. Well, ghosts, willows, stars, Zhang, wings and birds, these seven stars make up the image of a bird. The spring equinox season is in the southern sky, so it is called South Suzaku for seven nights.

The four animal images composed of the above seven nights are collectively called four elephants, four dimensions and four beasts. The ancients used the appearance and arrival times of the four elephants and the twenty-eight stars to judge the seasons. The ancients saw the solar terms facing south, so there was a saying that there was a dragon in Zuo Dong, a white tiger in the right west, Xuanwu in the north and Suzaku in the south.
