In which direction is the history of Tianlong Star developing?

Draco is a constellation in the north. It is one of 88 modern constellations, which can be seen in the northern sky all year round. Do you know exactly where Draco is? What is history? Let's take a look at it with constellation knowledge. Direction: The dragon is located in the north of the northern corona. It really looks like a dragon winding between the Hall of Ursa Major, the Hall of Xiao Xiong and the Hall of Ursa Major, spanning the vast starry sky. The high dragon head is close to the Five Immortals and consists of four stars, forming a quadrilateral, of which the brightest two stars represent longan. Area 1083 square degrees, ranking eighth. The brightest star is Etamin with an apparent magnitude of 2.23. It is found that Draco in history is a constellation that can be seen all year round in the northern night sky. It is located in the north of the northern corona. It really looks like a dragon winding between Ursa Major, Xiao Xiong Major and Ursa Major, spanning the vast sky. Gaolongtou is close to Wuxian County and consists of four stars, forming a quadrilateral. The long dragon body encircles the North Star for half a circle. The faucet consists of four stars: 2, 3, 4 and 5. A straight line leads from the two stars in the faucet bucket to the north, and you can find the North Star. It is an arched constellation, which can be seen all year round in the northern hemisphere. On May 24th every year, the center of Draco crosses the sky. Tianlong constellation is the eighth largest constellation in the whole day. Alpha Star (right pivot in Chinese) in Dragon's End is a fourth-order star. Although it is not bright, it is a famous star in ancient Egypt because it was the Polaris 4000 years ago. Legend has it that there is a hundred-meter-long tunnel under the pyramid of King Chiapas left over from ancient Egypt, in the opposite direction to the dragon star Alpha. Ancient Egyptian gods looked at Polaris from the tunnel. Tianlong's head is located in the north of Wuxian County, and its long dragon body encircles Polaris for half a circle. Beta star in Draco (middle name Tian _ 3) is a G 2 Ⅱ yellow giant with a time of 2.79 and a distance of 3 10 light years. The gamma star in Tianlong constellation (Tianfu IV in Chinese, Eltanin in the west, translated as Dragon Head) has a brightness of 2.23, which is the brightest star in this constellation. It is a K5 Ⅲ giant, with a distance of 1 10 light years. NGC5866 is a famous E6p elliptical galaxy with an apparent magnitude of 10.0. The research history is about 2700 BC, and the right axis (α of Draco) is the Polaris seen by ancient Egyptians. Because of precession, it will become the North Star again around 2 1 0,000 AD. Although Bayer on the right pivot is named Alpha Draco, it is not the brightest star in Draco. Its visual magnitude is 3.65, which is one degree lower than the brightness of the brightest Eltanin of 2.23. There are several groups of binary stars in Draco that deserve attention. νdragonis contains two stars with brightness of 4.9, which are 62 arc seconds apart. You can tell with a telescope. R star (RDraconis) and T star (TDraconis) of Draco are both Artemisia variabilis. The R star of Draco is between 6.7- 13, with a period of 245.5 days; The magnitude of T star of Draco is between 7.2 and 13.5, and the period is 42 1.2 days.
