Depth analysis:

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. Horn, sound, rafter, house, heart, tail and dustpan constitute the image of a dragon. The vernal equinox season is in the eastern sky, so it is called the Seven Nights of Oriental Qinglong.

Fighting, ox, female, air, danger, house and wall, these seven stars form a group of images intertwined with turtles and snakes. The vernal equinox season is in the northern sky, so it is called the seven nights of Xuanwu in the north; 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 looked at the direction of solar terms in the south, so there were the sayings of left oriental dragon, right western white tiger, north Xuanwu and former southern suzaku.
