Kneel to know the stars in the night sky (observation record)

Simply write it down for you. According to the location and time (Zhejiang, around 9 pm in early July), look at the northwest sky first and find the Big Dipper. Looking west along the arc formed by the spoon handle, you can see arcturus (the light of spring night), and you can see Kakuichi (blue) at low altitude in the southwest of the arc. Then, due south, there is a bright yellow star called Antares, which is about as high as Cassiopeia. Its constellation is called Scorpio. Then look to the northeast, near the zenith is Vega (blue), which is very bright. Vega has a star named Tianjin IV at the lower left and Altair at the lower right. Both are blue, and the three stars form an almost regular triangle, which is called the Summer Triangle.

If you don't explain what this is for, I have to write an outline for you. Specific questions can be asked again, don't forget to give me extra points.
