Today, twenty years later, science is developing rapidly. At that time, my hometown was completely new, just like a fairyland. I took the expressway back to my hometown.

Everything in my hometown is refreshing to me: the former small building has become a high-rise building with hundreds of floors. Some people say that such a high building can't get up by elevator? No, in this era, elevators are out of date. There is an unbreakable bubble next to the building. You can pick up this bubble.

Let's look at the road again. It used to be bumpy, and there was a thick layer of dust when the wind blew. Now it is a wide road, and several cleaning cars come out to clean the road every day. There are also dense cypress trees on both sides of the road. There are also more traffic lights, which makes it much more convenient for pedestrians to cross the road.
