The handle of the big dipper points to the position of the four seasons.

The Big Dipper, as its name implies, consists of seven stars. This is an important astrology in the northern hemisphere. The ancients often used the Big Dipper to determine the orientation and season. So, do you know the four seasons of the Big Dipper? Is the handle tip of the spoon? Then let's reveal the knowledge of constellations for everyone. The four seasons position of the Big Dipper is 1. When the end of the spoon points to the east, it is spring. 2. When the end of the spoon points to the south, it is summer. When the tail of the spoon points to the west, it is autumn. When the tail of the spoon points to the north, it is winter. Bucket handle of the Big Dipper is divided into bucket handle in spring, bucket handle in summer, bucket handle in autumn and bucket handle in winter. Shu Tian, Tian Xuan, Tian Ji and Tianquan are composed of Dou Shen and Gu Yue Kui. Yuheng, Kaiyang and Yaoguang are composed of bucket handle, which was called Piao in ancient times. Difference: The seven stars in Ursa Major are called Little Beidou; The emperor star is in Ursa minor, and Beidou is in Ursa major. The so-called bucket is an emperor car. The Big Dipper is named α, β, γ, δ, ε, ζ and η respectively from the upper end of the bucket to the end of bucket handle. Ancient astronomers in China called them Shu Tian, Tian Xuan, Tianji, Tianquan, Yuheng, Kaiyang and Yaoguang respectively. Extend a straight line from Tian Xuan through Shu Tian, which is about five times as long. You can see a star almost as bright as the Big Dipper. This is the North Star. Extended information: between the dragon and the tiger, in the center of the north, there is a Beidou carefully carved with clam shells. The bucket is two people's calves. It can be seen that the ancestors began to worship Beidou as early as the Neolithic Age. On the lacquer box cover of Zeng Houyi's tomb unearthed in Suizhou, Hubei Province, a complete picture of 28 hotels (that is, 28 stars) was found, which is the material with complete names of 28 hotels found so far. There is an eye-catching graffiti in the middle, surrounded by the names of 28 hosts, with the black dragon in the east and the white tiger in the west, which is strikingly similar to the clam carving dragon and tiger in Puyang.
