Where is the obvious sign of Ursa major? On the tail

Q: What is the obvious sign of Ursa Major? A: There is a famous Polaris in Ursa minor in the northern sky. It's not very bright. We can find Polaris with the help of Ursa Major. The most obvious symbol of Ursa major is the familiar Big Dipper, which consists of seven bright stars. Arranged in a bucket (or spoon) shape in the northern sky, it is often used as an important sign to indicate the direction and know the constellation. Because these seven stars are easily recognized by stargazers, they become a group of obvious and important stars. The China star names of the Big Dipper are Shu Tian, Tian Xuan, Celestial Pole, Tianquan, Yuheng, Kaiyang and Ursa Major. The first four are called Dou Kui and some are called Xuan Ji. The latter three are called buckets. Modern stars are named Ursa major, Ursa major, Ursa major, Ursa major, Ursa major, Ursa major, Ursa major, Ursa major and Ursa major. Connect the two stars at the mouth of the barrel and extend to the mouth of the barrel for five times to find the North Star. These two stars are also called pointing stars. In ancient China, the seven bright stars in Ursa Major were considered to be in the shape of a spoon, which is what we often call the Big Dipper. The three stars η, ζ and ε are the handle of the spoon, and the four stars α, β, γ and δ constitute the spoon body. In fact, when looking at the constellation Ursa major, the shape of the spoon is easier to see than the image of the bear. The spoon is in the sky all year round, and the direction of the spoon handle changes in different seasons, just one direction in a season. In the words of the ancients: bucket handle refers to the east, and the world is spring; Bucket handle guide, the world is summer; Bucket handle refers to the west, and the world is autumn; The barrel handle refers to the north, and it is winter all over the world. There was no calendar in ancient times, so people used this method to calculate the four seasons. Of course, due to the rotation of the earth, this phenomenon must be seen after eight o'clock in the evening.
