How is the Big Dipper arranged?

The arrangement of the Big Dipper is as follows:

The Big Dipper refers to Shu Tian, Tian Xuan, Celestial Pole, Tianquan, Yuheng, Kaiyang and Yaoguang in the constellation Ursa Major. The ancients associated these seven stars together and imagined them as barrels of wine in ancient times, hence the name Beidou. The Big Dipper appears in different directions in the sky in different seasons and at different times at night.

The ancients defined seasons and climate with the four fingers of Beidou, and became the makers of the order of heaven and earth. The long harvest in spring, summer, autumn and winter storage seems to come with Beidou, which has become the center of all things in the world. The deification of Beidou evolved with the development of Beidou belief, which began in the Han Dynasty, where the northern and southern cultures merged, and lasted for thousands of years until the Tang and Song Dynasties.

In different historical stages, Beidou is often interpreted as different gods. The Big Dipper may have nine stars in ancient times, but its position and shape are different from today's. Later, due to precession or observation location, two stars were not observed, so it was called the Big Dipper. However, in the pre-Qin literature, there is still the saying that there are nine planets in Beidou.
