The fantasy composition of the Big Dipper is 400 words.

When I traveled to Guilin this summer, I saw the Big Dipper.

One night, the weather was clear and there were no clouds in Wan Li. All the stars in the sky are in front of my eyes, as if I were an astronaut walking in space. I was intoxicated with this wonderful fantasy when I suddenly heard someone shout, "Look, the Big Dipper!" " "The big dipper? I've only heard this name in the myth of Ursa major before. I know it's a part of Ursa major, but I've never seen it with my own eyes. At this moment, I heard someone shouting, but my mind was full of questions: Where is the Big Dipper? What does it look like? ...

I told my mother my problem, and my mother squatted down and pointed it out to me from my point of view. My mother told me, "The Big Dipper is made up of seven stars. It is shaped like a spoon and is also a constellation. " While listening to my mother's explanation, I looked in the direction of her finger and thought about the shape she said. I finally found the big dipper. When I saw the Big Dipper, I felt slightly disappointed and proud. Disappointed that I didn't see Ursa major at that time, I was proud to see the Big Dipper that many people have only heard of and never seen!

But why is it called the Big Dipper? By asking adults and looking up information, I know that these seven stars all appear in the north of the sky and are the brightest seven stars in Ursa Major. The ancients connected these seven stars and imagined them as a bucket of wine. Three stars make up the barrel handle and four stars make up the barrel body. Moreover, wise ancients used the change of the direction of Beidou bucket handle to distinguish seasons and provide meteorological services for agricultural production at that time.
