After 20 years, I will go back to my hometown and write 400 words.

Today, I finally have a chance to return to my hometown. I boarded the spaceship and took off.

Along the way, I found great changes in my hometown. It used to be a dark river, but now it has become crystal clear, and many small animals have settled in the river. Look at the road again. Spaceships and cars are flying fast, but the roads are spotless. It seems that the environmental protection in my hometown is one step closer. There must have been dust flying all over the road before. Pedestrians on the road are suffocating. My hometown has become more beautiful. No stinking rivers, no garbage, no dust. All these make me love this beautiful home even more!

Here we are, where I went to school when I was a child. When I came to the gate of my alma mater, I seemed to see the familiar back again. It is the kind teacher who is educating us. Looking from the gate, our alma mater has changed and become more beautiful. Brand-new teaching buildings have sprung up and the playground has become bigger. I saw the majestic phoenix tree at a glance. His burly body has been our fierce sunshine for countless times and countless times. We played happily in the shade of the tree. I think of our childhood, the smiling face and the happy laughter. At that time, we were so naive, so naive and so lovely.

This time back to my hometown, my alma mater, which I haven't seen for 20 years, has changed a lot, and so has my hometown. Returning to my alma mater reminds me of us when I was a child, and makes me miss my childhood and my hometown even more. My hometown is unforgettable in my childhood!
