What is the letter in the Virgo picture, the one that looks a bit like me? What does it mean?

Follow the arc of the handle of the Big Dipper Ursa major, and you will find the alpha star of Shepherd, that is, arcturus. Continue to look south along this curve, and after a similar length, you can see a bright star, which is Virgo Alpha Star, which was called Kajupiter in ancient China. Alpha and gamma stars connecting Beidou can also be seen at a distance of seven or eight times. The ancient Greeks imagined Virgo as Demeter, an agricultural god with wings. She held the ears of wheat in one hand, as if celebrating the harvest with people. Virgo is the second largest constellation in the whole day, but in this constellation, only Cassiopeia is 0.9m, there are four 3m stars, and the rest are stars darker than 4m. Therefore, although Dmitry is the goddess of agriculture, her image in the sky is not too dazzling. We might as well simplify this somewhat complicated big constellation into a capital letter "Y": take the α-γ star as the handle, and divide it into two branches, γ, δ and ε as one branch and γ, η and β as the other. Fortunately, having a bright star, arcturus, did not make Virgo, the famous zodiac sign in spring, too dim (Virgo is also called "Virgo" in the zodiac sign). Kakuchi is the 16th bright star in the whole day. It forms a striking equilateral triangle with arcturus and the Leo beta star that we will introduce later, which is called the "Spring Triangle". The diamond composed of the Spring Triangle and the Alpha Dog is called "Spring Diamond", which is said to be a gift from Zeus to his sister Demeter. When we look at the stars in spring, we should find this big triangle immediately after finding the Big Dipper in Ursa Major and the North Star in Ursa Minor. In this way, it is much easier to find other constellations.
