How to write my essay on wandering earth?

The essay of Wandering Earth is as follows:

I landed on the moon again. It's the beginning of the lights. I'm alone on this bright star ball, surrounded by many immigrants from the earth. Everyone passed me talking and laughing. This is a brand-new planet, bearing countless fresh hopes, which is quite different from the photos I saw in Lu Yu 60 years ago. At that time, I couldn't imagine that this barren land had become a prosperous place.

I avoided the noisy crowd and walked into a quiet street. Walking, yellowing memories come to mind. After careful calculation, Lu Yu has been away from me for more than 20 years. He died on a mission to the moon. Now I am the only one who keeps the original agreement and will see the moon 20 years later.

When I was a child, Lu Yu and I were neighbors. He is five years older than me. He was so obsessed with astronomy that he even saved pocket money for a long time and secretly bought a small astronomical telescope. He always knocks on my door after school, takes out his telescope from his schoolbag, and then excitedly tells me what he knows about the moon: "Do you know? The moon rabbit landed successfully! There are traces of liquid water on the moon, indicating that there are creatures on the moon. "

At that time, I was not interested in astronomy and geography. Whenever I listen to him share with me that "man may be able to move to the moon in the future", I always give a perfunctory answer: "But China people haven't arrived there yet, have they?" "Then this task to us. The teacher said that China's dream of landing on the moon depends on our generation! " I shook my head while doing my homework: "We ordinary people are not qualified to dream on the moon." After a long silence, no one spoke. I looked up and saw Lu Yu looking out of the window and muttering, "But I think ordinary people also have the right to look up at the stars." I don't know why, I was deeply moved by this sentence and began to play with astronomical telescopes and study the moon with him.

One year before the college entrance examination, his mother took him to a distant relative's house, and I lost the news of Lu Yu.

The members of the "lunar exploration program" first met at the aviation base ten years later. Lu Yu didn't seem surprised when he saw me. She smiled and said to me, "Look, the dream of the moon in those days will come true now?" But no one knows which comes first, tomorrow or the accident. Lu Yu had an accident in a moon landing program. At the last moment of his life, he called me on his walkie-talkie: "Yi Xi, stick to it. After the successful migration of human beings, look at the moon for me."

Today, with his long-cherished wish, I boarded the planet where people come and go, and watched Lu Yu's dreams come true one by one, and I had mixed feelings.

"I will explore more planets like a hero on the moon in the future!" A boy's childish voice interrupted my thoughts. I looked at a mother and son coming by. The little boy is sharing his dream in the air with his mother with great interest, just like us. I am glad to think that more people continue to explore the universe. May this future generation burn fire and expand the universe.
